Should I Go Home?

I saw this guy sitting at a bus stop in High Holborn. He'd obviously been out for the day, and it seemed he was trying to decide whether to go home or not.

Several buses of each route went past as I watched him check his phone several times, get up and walk around, send a few text messages, before finally sitting away from the bus stop on the ledge of the window of this building. He seemed concerned about something, but I'll never know what.

Maybe he had had a fight with his girlfriend, or boyfriend?
