Meet Brett Weinbender, my third cousin once removed

Today I said hello to my cousin, Brett Weinbender for the first time on Facebook. I wrote him: "Hey there, I am your third cousin once removed." He wrote back: "Dude ur like 50. You know its actually quite insulting that u would try some bullshit like this on me. Fuck off ........... Prick". His sister wrote me back after I said that he was "rude and ignorant", and she said: "my brother is a teenage boy, I don't expect him to necessarily communicate with someone he doesn't know in a friendly manner." At least she keeps her expectations low for him. That way she will never be disappointed, just pleasantly surprised, when he doesn't pee in the sink when he visits her.
