oops i forgot my keys and my phone

Have You ever been in situation when You realized that Your forgot Your keys at home and Your cellphone is also left there? You have no device to communicate. Your home is not on the ground floor, and it has only the windows on the roof, which are covered by a thick layer of snow. The door on the ground floor is locked and the door bell is not working. The only internet cafe You've known and was in convenient place near your home is close of repair works and there isn't another one in 3 kilometers radius - as You already checked that. You live in a kind of town where asking a stranger to call by his cellphone - is a void try - everybody is afraid they will be robbed even if You are not that kind of looking. The snow on Your roof windows is not melting - so it's about minus 10 by celcius. The most useful stuff in Your bag is money - and You are lucky if You are not very limited by the amount - which is not very useful at the end of the work day - when most offices are closed.
