what if u see shadow walking by while you were talking to your friends but did not know shadow passed by and after u finished talking shadow was behind u

This would happen:
Me:*talking to my friends*
Shadow:*walks by me*
Me:Thats the end of my story!
My friends:Lol thats epic
Shadow:*behind me*
Me:*turns around* Hey Shadow
Shadow:Hi
Me:Wanna hang out with us?
Shadow:Sure
Then the rest of the day we were playing video games :D

This is what would happen if Shadow did that:

Tailsica(me): *is talking with friends*
Shadow: *passes by*
Melody(friend): realy now? He kissed you?
Tailsica(me): dont bring that up.... *gets out of chair and turns*
Shadow: hello..
Tailsica(me): AAAHHH!!!! *brings out pistol and points it at Shadows chest* WHAT DO YOU WANT?!
Shadow: *raises hands* DONT SHOOT!!! I DIDNT MEAN TO SCARE YOU!
Ray(friend): she will shoot if you dont give her an answer...
Tailsica(me): *keeps pistol pointed at Shadow* well?
Shadow: i just wanted to say hi!!!!
Tailsica(me): *lowers gun and turns away from shadow and walks off*
Melody(friend): well. she has a short temper today.. shorter that her usual short temper...
Shadow: you got that right...

me: blah blah
friends:blah blah blah
shadow: walks by
me: ummmmmm... can 1 of u stand behind me??
friend:uhhh... sure?? y??
me: you will soon see...
me:*faint* wake up 30 mins. later... holy chiz??!!!
shadow: what??
me:i just had an amazing dream that shadow was standin behind me annnndddd.... AHHHHH!!!!!*faint*

I would invite him to come to my house to stay until he could tell me what he's doing on earth

I eould punch him in the face STALKERLISIOUS

Me: 0_0 ......... Hi?

Shadow: *smirks and moving even closer to me*

Me: 0_0 ......Shadow?

CENSORED

I would probably punch him in the face because that's my immediate reaction to a lot of things.

I would've been surprised and ask him why he is behind me!
