My car needed a long overdue cleaning, and I found a vile of white powder . Im pissed because I have no clue how old it is. I showed it to an RA friend of mine and he said it was old . Do I bring it up to my "BF"??? Of course he will say it is from this winter.... it very well could be. He is still in treatment. He could leave whenever he wants. Do I stay silent on this discovery?
