Was at some "food trucks and beer" in the park thing near my friend's place and they had some of those hot girls in skimpy outfits who hand out like shots of energy drinks or tequila or whatever to promote the brand. Explorative I know, but also free tequila.
Anyway, one was like "holy shit you have the hugest calf muscles" (I work on my feet and do a lot of hiking), and like kept going on about it. "Damn do you run or something? It looks like you have bowling balls strapped to your legs."
And I was a bit like 
I got a mild ego boost from that.
Those little comments can really be amazing for your short-term mental health. The other day some random person stopped at a red light on their scooter complimented my hair as I rode through the crosswalk.
My hair goes halfway down my ass. I've grown it for years and it means a lot to me. I mostly just wash and condition it and keep it brushed, and put it up for work. Nothing fancy. So it could use some extra care. Lately I've started using a bonding shampoo and conditioner to help repair the ends and occasionally some grape seed oil. So them complimenting it specifically when I'd been putting a little extra effort in absolutely made my day. I was smiling for the rest of the ride home. And I'd really needed a boost as my mental health has been record low lately.
I try to remember this as I go about my life, and give people little compliments when appropriate, in hopes that maybe they needed it, too.
Not in hopes they needed it - I'd rather they didn't - but if they did need it, hoping I could help.
Shout out to the comrade with the Munchausen/savior complex who hopes people are suffering so they can alleviate it. Gotta be one of my least favorite tendencies.
Lol idk about comrades but I definitely met some Christians like that growing up.
