I just carried 10 cups, 6 bottles, and 2 soda cans out of my room and to the kitchen. It took me 3 trips. This is nearly a weekly ritual for me.
Why did I end up with so much stuff in my room? Because my room is on a different floor than the kitchen. What usually happens is I'll go downstairs to go to the bathroom or something, realize I want more water or something, and get another cup and take it back upstairs, because I didn't think to bring the cup I was using downstairs when I got up for my other errand.
When I was a kid, I always thought stairs were awesome, and I really liked visiting my friends who had stairs. I thought those kids were so lucky... But clearly I was wrong. If I have my way, I'll never live anyway that has stairs between my bedroom and the bathroom and kitchen again.
