blood is thicker than water

I watch a college basketball game today with my nephew. The game is between my school and his school.
The game is crucial for both teams, for them to maintain a hold of the top of the standings, and for us to be at least in the middle of the pack
It was a close game, and just like any other game, there can only be one winner. It was them.
I usually feel sad after each loss but this one was different. This time it was different. I wanted to win but I don't want my nephew to feel sad for the lost
It's ok to lose a game, at least my nephew is happy
