DONT SHHHHHH! ME!

Don't you hate it when people Shhhhhh you? LOL Remember when your parents did that to you?

But what if a guy you were dating did this to you, constantly. This girl says the guy she's been dating for a month has the habit of 'Shhhhhhing' her in public in front of people.He does it in front of family, co-workers anybody. She has mentioned it before but he continues to do it.

He likes him but this is getting annoying. Any suggestions?
