I finished Portal 2 on Friday night. Well actually it was Saturday morning:
11:30 pm – I think I’ll play a little Portal 2 before I go to bed.
12:30 am – I think I’ll solve another one or two puzzles before I go to bed.
2 am – What time is it? Oh… One more puzzle then I’ll go to bed.
3:30 am – What the- ok, I really need to go to bed so I’m not a zombie at my son’s swimming lesson. I’ll just finish this puzzle and then go to bed.
5 am – That was a good game. It’s going to be a rough morning.
