My mother acts out on Mother’s Day

Every year my mom is pissed off on Mother’s Day. Idk why she hates it so much. She gives the most attitude and argues with everyone. Growing up I hatedddd this day because I knew what we had planned wouldn’t be done or she would lock herself in her room. I think she hates it because she thinks every day should be a day where you honor your mom. It’s kinda like how people hate Valentine’s Day lol idk but I’m gonna drop off my gift and dip because she is again as expected pissed off at the world🙄
