Sometimes I disgust even me

I got an e-vite to go to a party celebrating the birthday for one of my best friends. So I reply that I will be there without reading the evite. Turns out that there is a dress code in effect. So then I think, "Fuck that, I wear slacks, dress shoes, and at least a polo shirt everyday of the week. I'm not going to some BS party in which I have to dress up." I have a real issue wearing anything that might remotely resemble my work clothes when I'm away from work. My weekends are my time to not have to get dressed up. I understand if it's a wedding or something but not a birthday party at someones house. So I considered changing my e-vite response to "unable to attend." Then it occurred to me that I am a child. What a bitch move. To not go to a party that someone took the time to invite me to because of what I am supposed to wear is a bitch move. I'm off to self loath. Jack ass...out
