I gave up on passwords ever since I tried to set up a new one. I had typed in "penis" and the computer responded, "Sorry, your password isn't long enough".
The absence of a password on my wifi may explain the presence of our new neighbours who've anchored their houseboat off Riverbend.
They're the best neighbours to have: peacefully floating in the river, here today and gone on the next tide, and listening to good music - whether they like it or not.
