Isn't it weird if a stranger calls a teenage girl ...

Why is it weird? Okay, maybe not a teenager. That's a little young. But look, I'm 62. I'm a decent looking fella, and we don't lose our interest in beautiful women. I frequently compliment younger women, tell them they're beautiful. But I'm not hitting on them. I usually just pay the compliment and walk away. It's my belief that women should be told that people find them beautiful. And I have the courage to do it. Most men don't. I'm not looking for a little somethin somethin. The truth is, my ex wife is the only woman I've ever loved or ever will love. I'm just waiting for her to find her way home again. But I also love women, and I fear women don't get nearly the number of sincere compliments they deserve, so I take it on myself to make sure they get at least one. And that they also know that not all men that give them compliments are trying to hit on them. I just told a young goth chick last weekend I thought she was beautiful. Now, a young goth chick is definitely not my type, but she was beautiful. I told her I thought so because most of the world probably just thinks she's weird. The vampire teeth don't help that, but you know, she really was gorgeous. And she should know not everybody in the world thinks she's weird. Of course, I did refrain from mentioning the whole vampires don't come out during the day, but you know, that's just good manners.

It can be an inocent compliment but on the other hand he might "try his luck" and it can lead to bad unexpected events.  Take care !.
