For me, i don't get "visitors" that aren't family or friends and they all call before to let me know they are coming. In which case the door will be unlocked for them to come in.
Now, When we are home and i am not expecting a delivery or anyone over then i start asking...who could be at the door[DOUBLEPOST=1423575542,1423575489][/DOUBLEPOST]
Same here Zakis, my father-in-law and i usually fight on that back to the wall seat to watch people come in the restaurant.
Exactly and I been apologizing to people I date because I am totally listening to their conversation, I just can't help keeping an eye on other people as they move about. My friends are used to it when we eat though.
