Here is a question I have created myself and I want to use it in a self-created game. But I want to check if others can solve it. It is designed to be a little bit challenging.
I am standing around
All night All day
Have multiple guys in me
forever they will stay
no possibility to say
"Please go away"
Some of them sometimes leave for a while
But they are back by no later than closing time
The guys can be used for drawing
Do you know my name?
EDIT:
Maybe the closing time
-part is confusing. The closing time for a office is meant.
