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?
Fun fact! IME, most people learned to tie their shoes incorrectly. Myself included.
If you know your knots, I learned to tie my shoes with a “Granny” knot. If you tie your shoes with a square knot, your shoe lace problems are vastly reduced.
There’s lots of discussion on this around this as well as additional shoe tying improvements.
