I'm looking for a fic I read a few months ago.
In it Kurt and Blaine are in the car with their son who is being really annoying (kicking their seats etc.)
so Kurt threatens to throw him out of the car and leave him there.
This reminds Blaine of all the times his parents used to do this.
Blaine remembers different times were this happened (once when he was like 7 and the other maybe 14)
and he tells Kurt about it who promises to never threaten to leave their son ever again.
I would really love if someone could tell what fic this is.
