I reached out to an old friend I haven't spoken to in a while. He's getting married, and I know he doesn't have a lot of money. Since I do photography on the side, I sent him a message saying, "Hey, I know this is a big event for you, and I do photography on the side. If you'd like some engagement photos taken, let me know; I'd be happy to do them for you as a celebration of your wedding, free of charge." He responded with, "Haha, Good for you, already got mine done, by my fiancée's sister." His response, particularly the "Haha, good for you," kind of irritated me for some reason.
I do have some intellectual disabilities, so I tend to read into everything
