Don't mind me

There comes a time in everyone's lives when growing up is no longer an option; it is a hard requirement.

You may not be able to do something about it, but life does.
It comes down hard and fast.
If they aren't fast learners, they won't make it much further.

Next time you meet someone that's difficult and unreasonable, give them time.
You might live long enough to see them take a hit that's well deserved.
