i dont like when people just apologize to be polite over stuff that doesnt even matter like accidently bumping your hand when you both go to hit the elevator button at the same time. it doesnt piss me off it just isnt necesary. i actually offered my first sincere apology to someone at work for snapping on them a few months ago. i had just met them and was in a bad mood and just kind of yelled at her for a second i apologized the next day now we get along well. a meaningful apology goes a long way
