Tagging?

So my son evidently has an issue with “tagging” his name on everything. I guess I should be gratefully he doesn't tag his territory like a dog does!! LOL


Here are some examples:

My bookcase (carved no less!): Guess who will eventually inherit it? LOL

His dresser: (2 separate drawers)

What is up with that? He keeps telling me he isn’t sure why he does it. He also wrote his name in his closet with permanent marker- still haven’t gotten that off, even though I tried stuff that supposedly would take it off (such as that "Eraser" that is suppose to get everything off!).

Anyways, thought I would share my frustration upon finding yet another “tag”! :-)
