How to tie your shoelace

My father had passed in away 2005 and my nephew came to me and asked me if I knew how to tie my shoes. He then told me he had seen me bend over and tie them a few times.  OK so what?

Simple answer.

The first knot must be done opposite of the second knot.

I am right handed so I flip the laces right over left then the next right over left and that is that.
Wrong. That is a slip knot. May not even stay tied for five minutes.

First knot as a right handed person should be left over right then the next the regular way right over left.

This is a square knot and will not loosen till you loosen them.

Thank you
