One of my favourite comebacks to anything is to just say "your face is..." and then fill it in with whatever the person said to me. Generally, it works like an awkwardly-phrased charm. My friend Ian Sheh also likes to talk about faces, but in a different way. His Love Your Face project features over 100 different faces, shot super close-up, highlighting the diversity and beauty in everyone's faces.
Go and look at all the faces!
