Doors

I have some kind of problem. At school, guys hold open doors for me all the time, but for some reason, if it's a double door, you know, two doors side by side, I'll just go through the other door instead of the one being held open for me. I won't do this if they are just waiting, holding the door, but if its just a quick hold, I accidentally will go through the other door. Then I apologize a lot and thank them.

Oops!
