One of my coworkers just had a baby, so he left work today and won't be back for a month or more.

We (accidentally) took the client's website down for 3 hours, messed up our git repo and when we finally fixed both things, I had to spend the rest of the day editing fucking vector graphics (which I had never done before and completely suck at).

I never realized how much work this guy does or how important he is until now.
