It is scary, particularly when surrounding friends are all settling down and seem to be leaving you behind.
Well, I've had a guy try to convince me he was a spy. I was sat there trying to make conversation and he's looking about him like Blofeld was about to jump out on him at any second.
There was the guy who, after 1 date (and a decision on my part that there wouldn't be another) just wouldn't leave me alone (and I did spell it out to him there wouldn't be another). He sent me flowers every other day, turned up at my door and one particular Friday night I was wakened by him singing on the street up to my first floor flat window. Seriously.
Oh, and the time for about a month I'd get to work and there was a bar of chocolate on my desk EVERY day for around 1 month. I asked about and NOBODY had seen who put the chocolate there. I eventually receive a text message asking if I have been enjoying the choc. The sender wasn't anyone I knew because they didn't come up with the name on my phone (my number was available for people to see at work BTW). He finally told me who he was (the xerox guy of all people) and would I like to go out for dinner with him. I said thanks but no thanks (in the nicest possible way), and boy oh boy he wouldn't let up. I ended up changing my number actually.
