Same happened at my house, as it was a terrace, the computer was in a back room, the cabled street was at the front and he refused to go in the loft or sling the cable over the roof. He set it up with enough cable for me to it myself and left me to drill holes and tack to the wall. (well actually he didn't, the cable length was too short and he had to come back later with more, but it's the thought that counts!
).
edit
that is, tack it up the wall, through the loft and down again - he would have done skirting boards but I didn't fancy having a massive cable snaking right round the house!
