lost wallet and fake ID - WWYD?

I live near a high school where kids cut through my yard. Years ago I found a weathered lunch box in my bushes. I was going to throw it away, but there was a thermos in there that seemed to have something inside. I opened it and found a small amount of weed. (S thought it belonged to a particular neighborhood kid who had that reputation. )We weren’t sure what to do with it.(It is illegal in our state. I am against legalization, but it isn’t something I really care about or would call the police about.) Seems funny now–we mixed some kitchen spices like oregano, basil, etc. with the weed, and put it back where we found it! The next day, it was gone.
OP–you did the right thing. I never had a fake ID. But I did know of high school kids who had them at 16-17 when the drinking age was 18. My kids don’t know anyone who has fake IDs. Fortunately they have little interest in alcohol, and don’t associate with drinkers. I am glad the drinking age was raised. Alcohol is much less prevalent in my kids’ high school than it was in mine. Most kids do obey the law. (At my school, in the 70s, 18yos could walk to the local liquor store during lunch hour, legally buy beer, share with underage friends, come to class drunk…)
