My favorite way to tie a KIND TIE is with a square knot.
Right over left, twist, left over right, twist and -- TA DA -- a beautiful clean knot.
Actually though, there is no right or wrong way to tie one on.
That said, it is much easier to tie one on someone else, versus tying one on yourself, so grab that person you've been wanting to get to know better, ask them to coffee, and then share a kind tie.
When you give a kind tie, what you are saying is, "I accept you... Just as you are."
After you tie a kind tie on them, ask if they'll also tie one on you... I bet you won't be sorry.
