<human>: Can you succinctly summarize the text in 1-3 sentences?

Nothing is ever his fault, god forbid. He always blames someone else, I can't remember the last time he owned up to something. It's always been like this when I was growing up, and I get to hear all about how right he is and how stupid everyone else is. I want so desperately to throw it all back in his face but I don't know what would happen. At this point I've pretty well stopped caring though, I can't take all the negativity. 

Does anyone else have a parent like this or know someone? I guess I'll just give an example of today to explain it. He went to an event over the weekend and gave someone his email for a 7 day free gym membership or something. Today I got his computer shoved in my face while he pointed out an email and asked if I knew who it was (I didn't). That's when I got the story about him giving out his address. I just nodded and agreed with how horrible those people were for sending him that (the easiest way to get him to leave) but god I just wanted to mock him. Yes dad, you wrote down your email for a gym membership you'll never use. What the fuck did you expect?

I'm sorry if this doesn't make much sense, I feel so frustrated. I have no sympathy for him anymore. He's childish and annoying, he feels more like a little brother than a father. I don't know if I could sit him down and talk about how what he does isn't cool. The best I think I can do is just completely shoot down any conversation he tries to make about how he was wronged. I don't do well with confrontation so any help is greatly appreciated.
<bot>: Father doesn't take the blame for anything, it's always someone else's fault. I'm sick of it. Don't know how to call him out without starting a fight, suggestions?
