I never really understood this notion of acting grown up or "act your age".
At what age do i have to act grown up and what does acting grown up mean?
18 20 25 30 35 40 45 50 ect?
examples
you tell a funny rude joke and someone says act your age
you try to do a handstand in the middle of town someone says act your age
you wear certain clothes someone says act your age
you still like a childhood hobby later in life someone says act your age
you play a childish prank on a friend/family member or work colleage which you find funny but someone says act your age
