Let's say before departure, you seeing each other like the "common interest socializing event" , if you all having this leadership sort, whom go to organizing this table to table crossing each other eating one meal, really.

You can, and then the Judge given you all a new destination.

But you keep each other's phone number, at least like that?  At least in the future, you know anything on the TV looks like what story at all.  Sometimes you just standing next by each other, you get to feel something, sometimes its not a super close thing, but it is a friend thing. 

You feeling different, one extra things on your Line App groups? 

Just one extra name, you don't even know how it ends up there?
