BlueMerleGirl,
I think one clue as to why it keeps happening is you saying, "
. I used to play along and act like it was no big deal and say oh thanks and just tie it." And by that reaction from you, they thought you wanted to know--and are continuing to tell you.
I think you have a couple of choices:
1. Tell them, thanks, but you prefer your shoes untied.
2. Let it go--you can't control what others say and do--only your reaction to it.
I have folks telling me all the time that I am wearing mismatched socks! lol--and I say, "Yeah, I like them unmatched and I have an identical pair at home!"
Namaste'
