Someone you thought you were starting to take a shine to is going to disappoint you today. Something in their personality will put you off: their arrogance is a very ugly accessory, and it's not doing much for your interest level. Crushes can be fleeting things, do don't feel shallow if their actions kill off any interest you had in them. There is no need to tolerate a rude person, no matter how attractive they are, or how powerful they may be. Just move on.
