Don’t ever try to play that “I have it worse than you do” game with people.
Don’t ever try to minimize someone else’s problems or invalidate their feelings just because you or someone else may have it worse.
To imply that their problems “aren’t that bad” or their feelings are “irrational” is very insulting and unnecessarily rude.
That’s an insensitive, inconsiderate and horrible thing to do to someone.
Don’t be that jackass.
