Turn computer off ready to go to bed.

Remember I need to check train times. Check times in app. Note that I could get advance singles for £10 less than standard return. Discuss return train options with T, agree which train seems likeliest, click book. App gives error message.

Try to book on T’s computer. Can’t check out as guest as email already registered. Can’t log in as no idea what password is.

Turn on my computer. Password not saved in browser. Request password reset. Look at password requirements and decide I’m too tired to think of something that meets them. Turn computer off and go upstairs.

While brushing teeth, think of another couple of options password could be, or could be changed to. Also realise that I could check out as guest using the version of my email address without a dot between first and last names, as gmail thinks they’re the same. (This is surprisingly useful as I often find myself unable to use my main address on services where I’ve deleted no-longer-used accounts.)

Go back downstairs, turn computer on again. Search for tickets. Get through to railway company website only to discover that no cheap tickets now appear to be available for outbound train.

Scream and head off to bed, half an hour later than originally planned.
