"I'm doing laundry!? At this time? #college," Tsarnaev tweets at 2:59 am on Oct. 25, 2011. It is the first tweet that shows up in his feed.
"I wish laundry would make like a person and do itself," he writes in April 2012.

He's a fan of the television show "Breaking Bad." He likes cats and thinks Miss USA is "so sexy." "How i miss my home land #dagestan #chechnya." His niece, he says, is the cutest in the world.
He complains about the food at college. Mentions craving junk food. Celebrates pizza. Brags about his skill at beer pong. "I am the best beer pong player in Cambridge. I am the #truth," he writes.
He even flirts. "you eat pizza in bed? i see, greek girls like their bed all greasy," he writes to a young woman on Twitter.
Tsarvaev gets locked out of his car. Scolds himself for being late to work too often. And he explains why he likes his job as a lifeguard at a Harvard pool. "i didn't become a lifeguard to just chill and get paid, i do it for the people, saving lives brings me joy #lifeguardoftheyear," he wrote on May 29, 2012.
There are a lot of jokes. "That awkward moment when yoloers end up living twice," he writes.
There are glimpses of loneliness and alienation. "Brothers at the mosque either think I'm a convert or that I'm from Algeria or Syria, just the other day a guy asked me how I came to Islam," he writes.
On another occasion: "how i miss my home land #dagestan #chechnya."
Some of the tweets now have a menacing tone.
"to some a hero and to others a villain, i say f___ the others"
"i love that great feeling when you know victory is certain"
"i won't run i'll just gun you all out #thugliving"
"If you have the knowledge and the inspiration all that's left is to take action"
Perhaps most disturbing are the tweets that come after the attack.
"Ain't no love in the heart of the city, stay safe people," he tweets just a few hours after the attack.
"So then I says to him, I says, relax bro my beard is not loaded."
"Nowadays everybody wanna talk like they got somethin to say but nothin comes out when they move their lips; just a bunch of gibberish."
"I'm a stress free kind of guy."
"Attitude can take away your beauty no matter how good looking you are or it could enhance your beauty, making you adorable."
"There are people that know the truth but stay silent & there are people that speak the truth but we don't hear them cuz they're the minority."
Perhaps the most bizarre tweet was in response to a parody Twitter account called @ImReaTed. "Ted" tweeted a photograph whose caption claimed "This man was going to propose to his girlfriend. She was at the marathon in Boston. When the man heard what had happened, he rushed over there. He found his love dead. If you really care repost and tag to prayforboston."
"Fake story," Tsarnaev wrote.
