A guy I had a fling with 2 years ago contacted me on Facebook messenger. He's written to me a couple of times last summer, but I didn't always answer. Now he wrote to me again asking for a favour. He told me that he is starting up a business and if he could practise speaking to me, and then he asked for either my Skype or phone. To me it seems like a lame attempt to get my number, but I could be wrong. Either way, he's not gonna get it.
