Its one of the few advantages about having a step parent..I dunno.

I got lucky that SD never wanted to use my stuff. I'm very possessive of my things, and it would not have been pretty.

Oh you know, what's dad's is theirs, what's yours is theirs, what's theirs is theirs. Entitlement.

Teens think that being rude is excusable with a J/K! Not so fast Nontax-paying-drains-on-my-money. The answer is no until they learn that HATE is a powerful word and cannot e used lightly. You either hate or not hate. There aren't any levels of 'hate'. So them hating you makes all your personal possessions completely and utterly yours.

And bicycles and pets and rides in your car and gifts and ...

I wonder sometimes if its because their dad loves you so emulating you (in their mind) will make their fathers love them even more? P

No just SDs, but SSs too! My SS15 used up all my face wash with out asking. I told him not to touch my stuff, if he needs anything to let us know and we will get it for him. Guess what, he still would use it. Now I have to hide my stuff from him. He thinks what's his is his and what's mine is his. Drives me NUTS.

i used to get so upset about the same issue,

when i told my husband, he said "so, we are family" families use stuff.

So, from that day forward, if they use my shampoo etc etc. i don't care, it is trivial, i just go to the store and buy more with his money, lol.

but still, i will hide certain things i don't want them taking, and i have done the speech, if you want to use something of mine, i will always say yes, but i still want you to ask, that way, i will know if i need to replace it, i don't want to be in the shower and can't condition my hair cuz you used the last of it.

it has worked.

I did tell my ss that my stuff was off limits. The kid would not even speak to me- just consistently pretended I was not their for years. If I tried to get his attention or engage him then I'd get the nastiness and rudeness. He got on my laptop one day without my permission, I had left it logged on. Actually me dh told him that if he did not want a relationship with me- which is what he'd co sisterly say- then gee, he didn't get the benefits of one either. So dh definitely got some points that day.

Also because I can be a snarky bitch, I'd help myself to something of theirs. You could be really blatant- like put on a ridiculous looking top of theirs or something and wear it around the house. Wait for her to say something. Then shrug your shoulders and say, "what's the big deal? We're family, right"

I had to wrap my makeup boxes in sheets and hide them in never used lenins to keep Snooki from taking all my stuff.when she was a young teen.

Nothing like having an important meeting and discovering your mascara is vanished!!!
