I've just got home after leaving my mobile at home and found a couple of messages from Anna.

She reckons that yesterday she had a big row with her Mum which from past conversations occurs occassionally, and she didn't want to talk to anyone which is why she didn't reply to my text or call me. Ok, I know we should be able to talk to each other about everything, but she's like me in that respect. I've done the same thing in the past, and have actually even done it since I've known her. I've been so used to not having anyone I feel I could talk to, that it didn't even occur to me at the time to speak to her about it! So, right now I have no reason to think she's lying in this instance!
