I like the guy at work much better than the hike guy. Agh!!

Yes, I see the validation factor now that it is being pointed out. I've been tempted to tease him but have not crossed that line because... well... work. He treats people very well at work and seems to be very much liked by his peers. Does come across as a genuinely caring person. But then again... validation? Food for thought.

Thus far, although perhaps borderline inappropriate, I think it's harmless. He's never made me feel uncomfortable nor threatened. I'll just admire from afar and in the inside.
