Isn't it obvious?
Get off the stove burner!
Then you probably are.
Say thank you?? That's what I usually do when I get a compliment
I should just accept the complement and not worry about context, but I'm not overly confident and always wonder if there's a hidden tease.
I thank them and then return the compliment! :)
In person or online?
If you think they are cute or hot you could give them a big hug and maybe a kiss on the cheek. If you don't then just say thanks.
I thank them for the compliment, even if I know they mean my flesh is hot to the touch and I'm probably racking up a fever...
