I hocked my first loogie the other day. I don’t know; something got caught in my throat (the pollution is really bad here), and I just decided to go for it, right out in public, no attempt at being discreet. So I did it, and no one noticed! No one even looked for a second; it was completely normal and acceptable. As for me wearing socks with my sandals; well, that is weird, even here in China. That’s only acceptable for farmers (random, right?) and old people.
