"You know, I feel kind of bad, keeping all the fun to myself like this," Summer said aloud while still holding Crissy and Alex tightly in her left hand. "I'm thinking of going to a friend's house and showing you around."
"Summer, don't!" Crissy warned.
"One's enough," Alex added, but Summer was not listening to pleas.

"Whatever. I'm the big one here, so I get to decide what to do with you. And you're coming with me to _______'s house." With that, she stuffed Alex and Crissy into the same jeans pocket and pulled on her boots to go outside. She also took the shrinking/growth formulas and dropped them into a plastic bag that she could take, in case they wanted to experiment more later.

Which friend was she visiting? (Both are 13)
