At my old church, I had a 60 or 70 something year old man tell me I was drop dead gorgeous every Sunday morning.
But that wasn't the weird part. The weird part was that he kept buying me shoes. He later told me he had a women's shoe fetish and often wore them himself. (Yes, he wore women's boots and women's jeans to church as well)
In his defence, he was a recent church goer who served in the Vietnam war, was an alcoholic and drug user and seemed to suffer from mental issues after such horrific things he has witnessed in his life.
I maintained safe boundaries with him so he wouldn't stumble, but I often laid hands and prayed for him and told him what Jesus had rescued me from. I don't think he had some lust issue over me, I think he was just trying to word his appreciation in the only way he knew how. He also often pointed out that I was beautiful inside and out, and apologised if it seemed like he was hitting on me. He seemed genuine. *Shrugs*
