new old house?

now, i am going to assume that there will be some quirks involving the ownership and living in of an old house. i think that is to be expected. there are some creaks and some groanes as well as a boiler that is sometimes loud. we don't exactly know when the wiring was first put in but we do know that at least some of it has been updated to present code. so far so good.
i used to work at a shop where from time to time a car would come in to get fixed and it would magically develop some other major problems that would be very sever and need to be addressed (like the transmission stopping working) and we would have to call the owner and tell them. The conversation would go like this
ME. hello sir or madam, your car is fixed but it is also screwed up.
THEM what did you do?
ME nothing, it just died, we didn't touch that part of the car
THEM well you must have done something cuz it was working when i brought it in.
ME we fixed the flat tire like you asked but now your tranny is busted. not our fault
THEM cars don't just stop working
ME that is exactly what they do, what are you talking about?
THEM this is a high quality cavalier and i want you to buy me another one at full cost!
ME here is a twenty, go get another
THEM and here is 13 change.


now i an awair that things happen but i just want you to all know that the plumber is at my house and now the phones don't work! must be his fault
