Re: How to get my GF to Start Smoking...
You just want to be careful that you're not making her feel like she's seriously changing who she is or her beliefs...that could create a slippery slope that's no good for the relationship. Let her know when you're doing it and offer to let her enjoy the company (no smoking required), then you can offer the hookah but don't force it.
