the key that opens doors

Imagine you’re walking inside of a building and the person in front of you, also walking inside of the building, decides to hold the door open for you. 

Just as you are walking through the open door, you notice someone coming in right behind you.

What do you do?

I’m guessing you’d probably do what was done for you. 

Well, you don’t have to imagine, this happens all the time. 

You’ve probably held your fair share of open doors. 

Well, since the door is open, what else has been done for you?

Imagine what might happen if you held the door for someone else.

Well, you don’t have to imagine, you could do it and see for yourself. 

Do unto others what has already been done unto you.

Keep the doors open.
