I've had some good news this week, and am going out with a friend on Saturday for a drink to celebrate. Another friend from a completely different part of my life asked me if I wanted to go out, and I told her I already had plans, but because I hate letting people down, I invited her to come along too. My DH says I've been silly to try and mesh completely different friendship groups - is he right? Did I do the wrong thing, and will everyone just feel awkward? I just wanted to be friendly. As a group of three, we don't have many things in common!
