Yeah but nah but yeah

Just give a quick "oh, thank you" in a pleasant, surprised tone. Comes off as gracious, but not conceited. Unless it's something you can't help, then it's more charming if you act like it's a skill in a cheeky way. I.e "wow you're tall"

"Thanks I've been working on it"

It's worth noting, you'll come off as more awkward if you try to fire back a compliment yourself. It came organically to them, and isn't necessary to mirror, unless you feel like they're fishing.

A word of advice. Either compliment them back or better simply say Thank you. Thank you is the best responce to a compliment.

I totally relate to this meme.

I just assume everyone hates me and go about my day based on that.

Giving complements feels better than getting them.

Just don’t make a big deal about it. A simple ‘Thanks’, or, if you’re feeling really strongly about it, ‘Thanks so much’. That’s it, don’t go anywhere else with it or call it out with some special recognition. Unless it’s sexual favors, that’s cool too.

this reminds me of what i like about public voting.. that one guy who upvoted my stupid comment that nobody else liked, two days after i made it.. i go visit that guy's profile and upvote a couple of his, or at least check out what that person is concerned about..
