<human>: Long time lurker, first time poster here. Wanted to share with you my TIFU from Thanksgiving last night. 

The background: this particular side of my extended family has never had a "normal" holiday dinner. At least one fight or argument will break out, guaranteed. Last year was particularly hilarious and it kills me that I have no record of it, so this year I decided to set up a twitter account just before dinner so that I could capture any funny quotes and arguments should they come up. As usual, the family did not disappoint. At points, relatives were yelling at kids, arguing about marijuana legalization, and suggesting Obama is mentally ill. I captured choice moments via Twitter and no one was the wiser, so I thought. 

Turns out one of my teenage cousins, hooked on her smartphone and obsessed with social media, saw what I was doing next to her and while I was tweeting away, looked up the account I was using. After we left, she showed it to her mom, who told my grandparents. My entire family now believes I was maliciously broadcasting our private family dinner to the whole world. Despite my explanations that the account was brand new, with no followers to see the tweets, and no personal info, they don't care to understand and think the whole Internet is out to get them. Now I'm eating leftovers and avoiding eye contact, while you could cut the tension in this room with a knife.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: tweeted my dysfunctional family's Thanksgiving dinner so I could have a record of it later. They found out and now I'm the family pariah.
