Is OTHER wrong in the post ? POST : I was throwing a party since my parents are away and this is the first time I've ever done this and was nervous so I only invited 10 people. My mate who I didn't invite went to a concert that night but I didn't invite him anyway as I wasn't that close with him although I've known him for years we have never really clicked. But today he messaged me after the party saying his disappointed that I didn't invite him and is annoyed at me for betraying him. 

So am I the asshole??
