Mine was when I first played source and ran around shooting a deagle as fast as I could and never stopped running and headshot everybody. And then I noticed how all of the kills everybody got were headshots.
Then I looked 40 minutes later and it was still all headshots. Then the funniest part was I stopped running to aim at somebody and it didn’t hit them.
So then I jumping headshot three people with a usp while running and realized I knew why I didn’t play source.
