Not all girls are rats or have big mouths...I've known a few that where trust worthy but it is very hard to tell at first...I just met a girl who I think so far is very much like a guy when it comes to weed.She has her own script and couldn't believe it when I told her that I talk on this site.Anyway she's one of those rare women,you know.
Besides most guys I know I don't trust either.
I don't think this is a gender issue.
