He keeps knocking your door even when you aint got parcels
dont wear them next time and compare responses. (dont think there will be a dear bb column this week =S)
He will give you a special delivery.
If he comes back the next day
As a one time postman it was my duty to always put it in the box hard so it would not fall out
Ask him if he has a package for you :P
Wear them again tomorrow and ask him if he likes you're pj's if you ask him I bet he will give you an honest answer...
