On the roof of my friends house. On new years eve.
The party was too noisy for me to hear the client over the phone, so I was milling around the appertment until I no longer heard the noise.

Sat down, took laptop from backpack, solved issue, wished client a Happy New Year.

Packed in laptop. Stood up, realised I had somehow wandered out of the appartment and up onto the roof.

Sat down again. Vertigo.

Opened the laptop again, sending the client the bill at 500% overtime rate.

At least the fireworks were pretty.
