Meeting strangers is the best way to make new friends!

never ask them "Why don't you talk?" or "Why are you quiet?" They hate that.It's rude.Don't

do it.If you're shy and you want to get into a sociable group,then just try to get a little attention,

but try not to overdo it.No one likes a showoff.And remember that each group will be different.

Observe what is appropriate for each group,and act accordingly,but don't change yourself

just to fit in.
