It’s society today that we compliment each other on social media If they have posted it. Youth culture today contains a lot of complimenting and the phrase ‘coddling’, lots of people support one another. I guess this leads to people wanting more attention and judging e.g instagram likes but that leads onto a whole another topic. The girl with acne situation - the right reply would be to lift the person up, saying it is their own choice and thats okay, so many people have acne and it’s okay to cover it up.
Giving someone support during a rough patch makes complete sense.
