When you are on the couch sick, but still want to go to FRC because it is your team's last day. (We are shipping the robot one day early to give it an extra day through customs)
When you were running a fever last night (and tried to hide it, but didn't quite manage it...) and you still stayed till 11 PM!!!
When both of your parent have lost bets, resulting in them wearing a mohawk. (Why else do you think I was up so late? Dad, it is your turn
)
