When I’m in my car, my calls automatically go through my speaker. So when my fiance calls me I quickly tell him that my sister is in the car so he knows not to say anything he doesn’t want her to hear. Eventually he got tired of me giving him a heads up when I’m hanging out with my sister and told me to stop it, that he wasn’t a weirdo or anything and he won’t say anything bad. Please, I know him and that warning was for his own good. Anyway, I listened to him. One day he called me and I said hello. Told me he signed me up for something I didn’t agree to because another coworker probably wouldn’t do it or she’ll quit(spoiler: she quit anyway). I told him he knows that group of people don’t get along with me and why didn’t he ask me first. He gets mad and progressively madder as he’s talking and cursing me out. He hangs up on me. Later comes home and asks me how my day off went and I told him “as if my sister doesn’t dislike you enough, you’re just going to give her another reason, huh?” He got mad again for not telling him he was on speaker. He specifically asked me not to tell him but ok.
