My Secret Crush on My Friend's Dad

So here’s something I’ve been hiding from everyone. Since my best friend Lily started spending more time at her dad’s house for weekends, I kinda… developed a crush on him? It’s not that he’s super hot or anything, it’s just his calm demeanor and how cool he is with the way he handles stressful situations that got to me. I keep finding excuses to go over there, but every time I see him, my heart skips a beat and I get all tongue-tied. Is it weird that this crush isn’t romantic in any way, shape, or form? It’s more like an admiration thing, but it feels so out of place! Am I just being ridiculous here, or is there something normal about feeling respect towards someone older as a friend's parent?
