Had this happen at work today and my colleagues looked at me like I was a madman for tying both shoes again, instead of just the one that got loose. But doing both shoes again just makes more sense, because you ensure both shoes are equally tight again.
Am I just weird for doing this?
Oh gawd no! Saw someone say they never thought about tying both shoes before in the comments here, but doing that would never have occurred to me. Yeah, you really must be a psychopath to do that.
