Human vs bathroom door

I seem to have a history of walking into inanimate objects however THIS TIME IT IS NOT MY FAULT. All of the doors at work are different weights. Not even consistently across door types. This means one of two scenarios typically happens:

1) I fling the door open like I'm acting out some emotional scene in a soap opera and damage the wall/inanimate object/human being behind it

2) I don't use enough force and it only opens wide enough to get one half of my body through it resulting in yet more bruising on my right hip. 

The office door is of the light variety. The bathroom door is of the heavy variety. So far I have been unable to exit the bathroom without getting hit or even worse shut back into the bathroom. I'm hoping that all of the witnesses to this event will just put it down to my being foreign and us not having this situation in my home country.

And by this situation I mean doors.
