I was at the mall with my girlfriend earlier and tried on a pair of sunglasses that I liked and she just started laughing because she didn't think they looked good on me and I got mad and walked away and gave her the silent treatment for about 30 minutes and finally told her it was rude of her and she told me she was sorry but I was being butt-hurt and it's not that big of a deal so I left to go home by myself because she didn't think it mattered. I couldn't even explain why I was irritated for the longest time because I didn't even understand why it made me so mad. I hate how irrationally sensitive I am but I couldn't stop being mad about it until an hour later when I talked to her and apologized. This is kind of a vent and I want your guys opinion on if I should of been mad or not but mostly, what can I do to develop thicker skin?
