I'm not very excited about my valentine's day gift
Why are you not excited about your Valentine's gift?
I'll sit on a couch and watch a movie alone, eat some chocolates and that's about it.
It may come off as rude if you reject someone's Valentine's day gift. Being ungrateful will make people not want to give you anything in the future.
Valentine's Day is not a big event for me. I should have tried to see if he wants to spend time with me, but I already knew that I'm going to spend my day alone anyways.
It seems that you are down about the holiday itself and if you've had bad relationships leading up to that day, then it's understandable. However, thinking negatively about Valentine's day will only lead to you having a negative experience. You will attract what it is that you focus on.
