That awkward moment is when someone who used to be very significant to you tend to be nice to you
and it is even more awkward when you also behave nicely
you can even make jokes!
Oh my... are you losing your senses or what?

Too awkward, too weird, too unexpected to digest.

And now... all the nightmares...
All the dream that came to you while you were sleeping...
Suddenly become dejavu... *gulp*
