Dude. The 2-year old pizza thing was a joke.

Anyways...

He was living alone at the time (conversations with Kirito prior to GM announcement) and was ordering pizza. He never answered the door though because SAO so the pizza guy left most likely.

Then, the SAO incident was televised and his family/friends/co-workers likely checked on him (he was in line for a whole night prior to SAO, implying he is a hardcore gamer) as he might be in the game.
