[REQUEST] NPCs that hold open a door for the player

[SyntaxError73]

I am Requesting a hopefully simple mod that lets NPCs hold open a door for the player, so that you may go inside without needing to "interact" with the door. 
Say you wanted to go into the shop in Riverwood.... Sven could offer to open the door for you, you reply "thank you, that is very kind", and then you are instantly "transported" to the interior of the store in Riverwood.

 

Just thought skyrim needed some politeness (and a way for me to go into buildings when I cannot use my hands)
