Five Seconds in an Elevator

My grandpa lives in a nursing home on the third floor, and sometimes I find myself alone in the elevator for five seconds or so. It got me to thinking about what people do alone in elevators when they know the door could slide open as soon as the next floor. I'm not talking anything gross here, but I think the answer would have to fall in one of two categories - "picking" or "adjusting". That's all I have tonight... ciao!
