What would you do if Sheldon came knocking at your door saying your name endlessly

Honestly, I probably would not hear it - my dog on the other hand, if she heard his knocking (if were not out for a walk) would alert me to someone being at the door.

I probably would be surprised to find him so far away from his stomping grounds, but I would invite him in and make an absolute fool of myself - be like Raj and not be able to talk. (Of course with this cold I can't talk much anyway - but I am not accustom to having stars come knocking on my door).

I'd answer the door.
