Over posessive perhaps.

She said you're guard-dog possessive.

I have this stickers all over my sationery. These translucent stickers with my name printed wide and big across them: LIEW MIN JUN. In caps, yes. Some of them even have details like 'Please call [insert number here] if found.' But, no, don't mistake me. I didn't put them, Daddy does. He has a fetish for lables.

I prefer to display my posession in a more subtle way. Sometimes, I don't really notice how openly I display it till I'm told. Like how I wouldn't let anybody touch my phone. I almost screamed at Palwinder once for even touching it casually.

When it's my property - keep your hands off.
