I shall definitely be deleting them. I just don't have the time or energy to be dealing with plastic people like that.
I feel really awful though because the lady I was going to meet today tried to contact me on facebook to see what was going on as she hadn't heard from me this morning and I had totally passed out on the sofa after putting Ethan down for his nap. Was just so tired, it was one of those moments where you sit down and next thing you wake up and when I woke up, it was 12:30pm. I apologised profusely to her and luckily she was ok, but I felt really rude once I realised she'd been trying to contact me. We've exchanged numbers now though, so hopefully we'll be able to keep in touch that way.
