The downside is that if she catches me smoking then she'll want to smoke, too. Its not a bad thing, really, but sometimes I just need some alone time. When you smoke with your girl she'll want to cuddle and shit like that. I just want to space out and listen to some music sometimes. Its difficult to explore your high when you have to give attention to somebody. Although, the stoned sex always makes up for it.
Sorry, I got a little off topic.
