Or overall gratitude? Let me give you an example. Back in college we had a friend who used to stop by all the time. There were 4 of us in the house and several other lingerers including this guy who was somewhat ocd. The guy used to take it upon himself to start cleaning our house for us, causing a shit ton of noise and complaining in the process about how unclean it was. Again he didn't live there. This didn't include our bedrooms which we kept clean, we just didn't have time to clean the mess in the open parts of the house because of how bad the partying would mess it up. College ya know. Anyway we try and tell the guy that he doesn't need to clean anything because we were trying to watch a movie and get high but he won't stop. Then he starts getting all offensive, saying things like "Im hear cleaning your house for you and I can't even get a thank you. You should be grateful" We tried to explain to the guy that we never asked him to clean anything, and also explained that he doesn't live there and shouldn't worry about it. It was pretty obvious to me that he was doing it because he was OCD or took too much speed. So who was right? Should we have been super thankful for his "selfless act" or was he just bothering us with his mental/drug issues in order to fish for clout? Egoism? At what point does a selfless act become a selfish act? We ended up kicking him out btw until he calmed down.
