I actually thought the post about being on the bus and getting ready to go to sleep got sent straight after I got on the bus at 11pm. But it didn't, and as I then switched off my phone and went to sleep, I didn't realise, and didn't get Chris's voicemail message at 1:30am. Woke up briefly just after 3am when the bus stopped for half an hour at Keele Services, switched the phone on for a couple of minutes to check for messages - at which point it must have sent the original post - but either it didn't report the voicemail message or I was still half asleep and didn't notice it. So switched it off again, and went back to sleep. It was only when I got off the bus at Heathrow and switched my phone back on again that I discovered his message and discovered that the original post didn't go through when I thought it had, leaving him looking at a message about me standing in a deserted bus station, and nothing further for almost 4 hours!
I'm really sorry, my dear!
