That was the twenty minutes that was

Remember the week that was, back in February?

No, I haven’t had another one. But said person from that week today created a new profile on the web site where we originally got chatting. I know that because he visited my profile, which leaves a trace, and ‘nodded’ – a sort of one-click ‘hello’. (Other greetings are available.)

And then in the space of about twenty minutes, he logged out; logged back in again; looked at my profile again; and deleted his account. (I didn’t visit his profile at all – I can tell all that from the way the web site shows my own visitors.)

Whatever can it all mean?
