Is there anyone you've come across, be they friend, family or acquaintance with the attitude that no one is good enough for them (even the ones who are) and yet, for all their apparent self esteem and high standards, they are very unhappy and negative to be in company with.

An acquaintance snarks about how irritated he is and how life sucks because he can’t find a partner he respects and he wants to be in a relationship, look to marriage & starting a family. At the same time, he puts down many of his friends/acquaintances for their choices (they’re mostly happy) by saying how desperate or old or stupid they must be to “settle” for less.
