I waited until Sunday to get a Hamster like you wanted. You said you are 95% sure the pet store we're going to is open on a Sunday. It will most likely close early. Please get up soon so we can go at a time when we're not rushing around getting things and what not because the place is going to close in 10 minutes or something like we always do.
PS. When I knock on the door asking you if you're getting up, don't just grunt things and try to go back to sleep.
