Well, I think I was a wee bit misunderstood when I posted this!!!

MiamiCubano, there sure as hell ain't any degree of financial dependancy or anything like that to my mother-in-law, I'd be in an unhappy world if I couldn't take care of my own. I'm sure like you are, I am a man who stands on his own two feet and I work my ass off for what I've got, so there's no way in hell I'd mix family with money, it gets wayyyy too messy.
It's really only a "respect" thing in the end. She doesn't prefer it, but if she ever got into my face about it, I'd tell her to get over it, or get a hotel.
Ultimately, as stated, it IS my house and I'm the one who pays the bills and I'm the head of the household. I will most likely smoke, she doesn't have a huge problem with it, but she'll probably give me a "look," to which I'll just smile and forget it. In the long run, it doesn't bother me immensely because, frankly, I've got people telling me to f*ck off every single day at work, so, suck on that lady!!
I really only posted this to see if anyone had any other stories of dealing with "in-laws." It's just going to be odd having her here for a week.
Thanks for the posts fellas!
