|The first paragraph has alot of duplication in it. We repeat the being tired way to much. I became bored with the eyes opening and all that. Cut out sleepily and slowly.
The second paragraph: I don't believe a door rips open.. A door bursts open possibly need a different verb there. The T-shirt is always capitalized. Maybe some names of these people would draw us in more. Instead of brother and I who are these people that are waking up.
The third paragraph: You need to explain more of your father on a grey suitcase. he seemed to have trouble, explain what he had trouble with.
The first dialogue was fine.
The second needs some help, if your finger was stuck in a suitcase you would not be greeting people nicely when they enter a room. Put yourself in the fathers situation, the man is in pain.
The next dialogue. Open this up or I'll get cross. Who says something like that? Their finger is stuck, they are in pain. They will be mad, angry. You don't tell it show it.
Your not going to debate about opening the luggage you are going to figet with trembled fingers as you open the lock. Your father is in pain.
The second to last paragraph is still repeating the first paragraph about waking up, this is getting old.
The last paragraph spends time on someone eating cereal really. When you can write that in one short sentence.
Story drawn out way to much. Sorry if I appear harsh, but it is necessary if you want to improve your story. I would start again and make this about something more than waking up and eating cereal.
