I'm guessing it's the shoulders... but instead of screenshotting their chart and making a passive aggressive meme out of it maybe you could just kindly ask them via comment instead? Just an idea...

The neck?

the neck is red the chest however

Meh, Maybe it's when you visit your relatives and give 'em hugs

on the chest?

Well, You don't exactly hug with your ears, What do you expect?

you dont touch the chest when you give a hug

Have you never given a hug before?

i have

So how did you avoid making your chest have contact with the person your hugging, The only way I can think of is if you're a spirit.

the meme is touch with your hand

Hand?
Well, Why does that even make curious? People give handshakes all the time or play games like thumb war
They even colored that on strangers!

Do you not touch your family?

not on the chest

Seriously, How do you hug?
