It can only mean one thing

The early start (there's a 4:30 in the morning as well ?), the cramped train journey, the horrible smell, the crowded public transport, the rude people, the dirt under my finger-nails when I got home, £2.80 for a pint of something flat that tasted like the dregs of what comes out of the pot washer.

It can only mean one thing.

A fantastic day out in London.
