Mom mad at hickey

Ok I didn’t even realize I had a hickey... I guess my bf got a little too excited since we haven’t seen each other in awhile. he usually doesn’t give me hickeys nor is it something i’d ask for but it just happened lol.... but anyways i’m 24 years old and I was eating dinner w my mom and she saw it and started acting really weird... she was like pissed off and mad about it. i mean I guess this whole thing isn’t a big deal but idk I kinda feel like i’m babied sometimes. i’m an adult. hickeys are kinda childish ig but it was an accident lol.
