Some background info. My friend Mark and I are close friends and met in high school, we smoke weed together frequently and buy off of another friend of mine named Tommy. Tommy and I were friends already before I met Mark but we both trusted him. So about 3 weeks ago, Tommy sells Mark 10 Grams for $100 when 10Gs is supposed to be $70. Tommy told me as a friend not to tell Mark because its a scam. Fast forward to about an hour ago and Mark is asking me if it were true that Tommy scammed him for the pack, I tried to lie in a panic, but ended up fessing about 10 seconds later and told him the truth. Am I the Asshole for not telling Mark sooner?
