Riddle

People walk in and out of me. They push and I follow. When they walk out on me, I close up and I stay waiting for the next person to walk into my life when I have a more open mind. What am I?

Choose an answer

A.A door
B.A revolving door
C.A gate
D.An elevator
Hint: It's a 2-word phrase with 10 letters, starting with "A".

Answer

An elevator

Why this is the answer

This describes automatic doors: people constantly walk through, they open and shut ('a more open mind') for the next visitor, and closing behind you completes the metaphor.
