When we got our new hoodies

When the models look longingly at everyone else eating chocolate on set

When someone asks if you want to go to the pub after work.

When the client asks about a specific line in the script

When you enter hour three of the pre-production meeting

When the client gets wind that sending an Adstream order is little more than pressing a few buttons

When you're so close to going home after the shoot but the DIT tells you it's going to be another half hour...
