Just remembered a case in point about drugs: I wanted to visit a major city some 250 miles away, to attend a monthly meeting of a gay naturist (nudist) group I'd never met before. Really! I also had been chatting online with a gay guy from that same city who sounded nice, though not a member nor interested in that group.
He offered to put me up at his place when I mentioned my plans online. That was a great deal, and I'd get to meet him, see how things played out between us, and I drove my car to his house. He seemed like a really nice guy in person, and I started to get my hopes up.
But I wasn't there a few hours when some real dirt-bag character rang the doorbell, and as I puttered around in the kitchen, I could overhear a drug deal was going down with my host! They stayed near the front doorway, perhaps because of me.
And I'm thinking: "This is the making of a classic drug bust, dummies standing in the doorway, and here I am, right in the middle of it. I may eventually be able to prove my innocence in court, or maybe not, but what a bitch it'll be! The police will arrest everyone in the house. I don't need this!"
I attended the gay naturist meeting that night as planned, some really nice guys. They accepted my application to join, and I learned the members offered lodging to out-of-towners in their own homes. I got the phone number of a guy who seemed eager to spend more time with me. There's nothing sexual during these club gatherings, BTW.
Next day my host did another drug deal while I was there, and was on drugs himself from what I could tell. That was it. I phoned this club guy from the night before, and asked him if he'd like to put me up for the rest of the weekend. He agreed, and I left for there almost immediately.
We became friends, BTW, spending that first night in his bed (which I never did with the first guy). I continued to stay with him for over a year during subsequent visits for monthly meetings and other trips to that city, becoming sort of long-distance BFs.
His only real drawback was a vicious dog that hated everyone but its owner, and had to locked up all the time I was there, and barked its displeasure constantly. We never did take it further, and eventually I moved away. To the list of non-leniency items I would therefore add: owning a dog that wants to kill you! LOL!
