If you let people down,
If you get someone off your back,
If you don't get around to something,
If you are short of or on something,
If you tag along with someone,
If you drive your friends away,
you behave in a certain way so they don't want to be your friend anymore.
you go along even if you're not needed or invited.
you don't have enough of it.
you disappoint them.
you stop that person from annoying you.
you don't find the time to do it.
