Spent about six hours writing tests and coding a user log in system for a Rails app last night. Finally finished at around 2:00am. Commited, pushed and merged, then called it a night.

Woke up today and Postgres is refusing to play nice. Spent twenty mins or so fixing that and then ran rspec.... Two thirds of my tests are missing - everything I wrote last night. I check my code and sure enough, they aren't there.

Wild panic ensues for a solid 5 mins before I realise I didn't actually pull the updated master branch after deleting my feature branch last night.

Now I feel like an idiot, but a relieved one.
