ways to know if they are really your true friend
1. They wouldn't change the destination last minute when they are told you the place already.
if they do, they are only treating you as a fool.
2. They wouldn't talk bad about you.
if they do, they are also not as good as what you thought.
time change everything.
if they do all that,
just to let them know that they are just selfish,
you don't care about others feeling,
and it's a wrong to be friends with them.
