"Uhh, sorry?" Alex squeaked as he stopped but didn't dare to turn, terrified that he recognized that voice. It belonged to Brianna, one of his little sister's friends. Alex didn't know much about her actually, just that physically she seemed to be unremarkable as she had a cute face but a thin and still undeveloped body, and that apparently she liked writing stuff because Janet casually told him she was busy reading her stories once as an excuse to not do her part of the chores. Alex still was scared, he really didn't want anyone to recognize him and he had no clue how to get out of this problem.
He felt his body tense up when hearing the girl walk closer to him, knowing that running now in clown shoes was impractical and would look very suspicious. Unlike some of Janet's other friends he had no idea how she felt about him, compared to some of other Janet's friends Brianna was the normal one, not being rude of awkward to him based on whatever lies Janet was telling them. The lack of information just made him a bit more scared about how she could react though.
Alex immediately looked down avoiding her gaze when the girl stepped up in front of him, thinking that she looked quite tall from this new perspective. He remembered she was taller than his little sister but without knowing her exact height he had no idea of how small he got after trying out the shrinking formula. All Alex knew was that he somehow felt younger than her in the current situation, where she rightfully chastised him for his clumsiness and he was clearly wearing clothes too big for his size, and all he hoped was that he didn't shrink even more right in front of her, or if he did that somehow she failed to notice something was wrong with him.
"Oh, you look a lot like him but you're not him. Alex is taller than me. Sorry kid" Brianna apologized. Still not looking up, Alex saw Brianna put a hand on her hip as she assessed him and thanked his lucky stars for not being recognized.
"You should still be more careful, got it?" Brianna chuckled and ruffled Alex's hair just as he was about to stammer it was ok and continue on his way. He blushed with embarrassment and somehow found the courage to look up and see the girl's half amused half mocking grin on her mouth. Alex nodded shyly while remembering something that was doing a number of him, how the few times he had seen Brianna she was polite but shy, but now she was so confident it was surprising. Was it just because he looked smaller than her or because he looked like a kid to him? He couldn't tell, but it was affecting him at some level.
"Alright then" Brianna nodded herself before turning around and going on her way. Alex wanted to sigh with relief but.. he found himself shrinking again! Looking up he saw the tall girl getting just that bit taller before his eyes and he panicked.
"H-how tall are you?" Alex blurted against his best judgment, making Brianna stop and turn around to look at him again. Alex didn't understand why did he do it, if it was because he needed to have an estimation of how small he was now, or if it was because one of the strange things he felt around Brianna was a sense of safety, but the damage was done anyway.
"Huh? I'm 5'7''... Why are you asking? And why are your clothes so big?" Brianna seemed to humor him because she had a question on her own to make, but at least she wasn't approaching again or seeing that he shrunk. With that information Alex was able to see he was probably around 5 feet now as the girl was pretty much a head taller than him now, would he get smaller than that? And of course, he had no answer to her question, now that he lost almost an entire foot the clothes were starting to look beyond oversized to him and he felt he would soon need to start grabbing his pants just to keep them from falling down completely.
"I umm.. umm" Alex looked down again trying to find a plausible reason
"It's ok.. it's not my business" Brianna apologized for asking and Alex nodded gratefully, blushing again while she kept staring at him for a bit. Now that he knew how small he was Alex hoped she would say goodbye again before going her own way, even if he noticed she was walking towards his block so she was probably going to his house to meet with Janet anyway. But at least once she was out of sight he could drink the growing formula again, get back to an acceptable size and avoid any questions.
What happens next?
