Xoel, first it's a great hookah and you'll love it, I won't go into more detail than that, simply bc I don't/can't blatantly sell in this part of the forum.
2nd, I can advise you on the wife situation, the whole pants thing, and I'm a gansta etc. Just use finesse with the wife. You have to make sure she feels as though she wins. You can't just jump into the bed and demand things, believe me, I know. You need to plan things out well in advance and be able to counter to what you know she will react. It's too ealry for me to go into detail and I have to run, but just be patient and make her feel like she got her way as you got your hookah
