This whole problem started last summer.
I got girlfriend of the time, who I'll call Sarah, in to smoking weed. We smoked quite alot, and she became a regular user.
Now, I have a good friend. I'll call him Liam. Liam goes out with Sarah's friend, who I'll call Amy.
Liam and Amy are a great couple, but Liam is right against weed and shit.
So, right, Sarah has got AMy in to weed. Amy is now a regular user, and Liam doesn't know.
Should I tell Liam?
