Actually, it's forwards

Just a minute ago, I was walking up towards these glass doors, and two janitor guys were walking towards me, on the other side of the doors. I made it there first, so I opened the door and held it up for them.
They hesitated.
I gave little wave with my arm, like a gentleman does…inviting them to walk through.
So they finally did.
The one guy said: Well, this is a little backwards.
Oh no. You are walking towards the future, my man.
