The problem is that I cannot remember my login details. At all. I have no idea what my name is. (Don't tell my GP! He'd have me incarcerated in a second.) As for a password - well, it could be anything. I didn't used to have a problem. I used the same password for everything. Then my brother ( yes him) told me that this was incredibly irresponsible of me because if someone hacked one account, they'd be able to hack them all.
So I started using different passwords. I'm sure that I was very inventive (while assuring myself that I'd remember these combinations of words/numbers/lower case/higher case/bla bla bla). Of course I don't know this for certain - because I can't remember them.
All this means that I daren't log out of any of my (absolutely essential) social media sites: Facebook (though I keep threatening myself that I'm going to stop); Pinterest (though I keep threatening myself that I'm going to stop); Twitter (though I kee........ You get the idea). It also means that I can't comment on anybody else's blog, because I don't know my name. Possibly this is a good thing, but I suspect not. I'd like to comment. I know how much I enjoy the comments that my blog posts get (thank you), and I'd like to reciprocate.
However, I CAN remember the very first password I used - for a long long long ago and now obsolete email address. It was a German word. Maybe that's the answer.
