Computer literate or what?

So I went to the dentist to have a broken tooth repaired,It's a village about 10 miles up the road,the dentist himself seemed a bloke with a good sense of hunour,and is a couple of years from retiring to go part time,so a man of much experience,job done and Sheila had a fun time listening to his dad in the office who is 95 years old and was waiting for his lunch,the dentist gave me an injection the second of two as it was a little deep,and said "back in a minute just off to check my lunch is ok,not a thing you usually encounter in the big city places,oops... can we say that about big cities?
He is an art lover and we talked a little about art,apparently his house is full to bursting with pictures he purchased,when I say we talked ,he talked and I tried to reply with grunts as he was drilling away at my tooth.
We are now awaiting our visitors Susan and Trevor,Sheila has made a curry which we hope they are not averse to,though I can't imagine Trevor being averse to anything,also she stocked up on Stones Beer,which I think is now brewed in Burton On Trent.
We had a problem with the wireless contact on the internet yesterday,if I turned on my new laptop it worked OK,but the pc of Sheila's would not let her onto the web,after thinking about it today whilst in the chair of pain,I figured that the location of the router might be the problem as it was below the pc,so decided to try connecting the pc to the router by cable,HEY PRESTO! it works,and I pick up a wireless signal on the lap top,probably I could just relocate the router to give a better signal to the pc,but as it is everything is ok,and nothing to do with skype as suggested by Montana Mike,(he has a down on Skype).
