The sweetest mom friend of your group :D Be a friend of an Ying Ting and you've got a friend for life. She'll always check in on you periodically to make sure you're doing well and catch up. A really fun thing that you can do with an Ying Ting is to force them to participate in loud and slightly embarrassing activities with you.
Friend: "Hey let's climb this wall!"
Ying Ting: "Wait people are looking! Omgee this is so embarassing~ ><"
Friend: "I have this problem"
Ying Ting: "Don't worry, I'll give you good advice and help you resolve it."
