Look at their hair.
If someone has a huge zit on their face, just look at their hair. Study the volume and try to figure out what hair color they have. It'll make you think about your own hair.
Close your eyes
Just...don't look at them.
Drop something for them to pick up, if they do, you can take it from them with a smile, their smile could be better than yours.
Look at their social media.
We've all done the same.
Think about their qualities and try to forget their flaws.
Think about something funny or uplifting about them.
BE A GOOD SPORT!
Make sure you support them and put their features aside, everyone is beautiful!
