People who make excuses for the other person but not for you
Like you have a complaint about someone. Could be anything. They annoy you in some way. And you'll be like "god I can't stand how my coworker is so slow and stupid."
And everyone will jump in with excuses for him. Maybe hes got mental or emotional problems. Maybe hes got stress at home. He has a medical condition that makes him slow and stupid, and boy I must be a real asshole for not considering his situation.
Well what about me? Maybe I have stress at home. Maybe I have a disorder that makes slow and stupid people intolerable. Maybe my emotional problems are affecting my judgement.
Then suddenly its "no you cant use excuses you just have to own it and deal."
Editing to add another example, had this coworker years ago who got away with everything because she always had an excuse. She got to sit down and take breaks every half hour because of "asthma" (whilst having a cigarette). She didnt have to do any lifting or anything because of back problems. She also got a free pass on every mistake because of "brain damage" from sleep apnea. Always spouting "I had 70% oxygen loss its not my fault $100 went missing!" And it was always fine.
Me, I was in a car accident and while I could show up and do some work, whiplash and some other injuries were slowing me down. You think anyone gave me a free pass?
