I so highly recommend saving specific, meaningful compliments, and giving specific meaningful compliments whenever you can.
Just got this today out of the blue. It’s not bragging to appreciate the good things of people. A compliment is a good thing.
All you have to say when you get one is, “Thank you :D” – mostly because it’s usually hard to think of something else… that is, unless you want to get into the game of complimenting back and forth with each other. That can be fun, although exhausting
