Hey, no need to slink off anywhere! We want you here

Funny, as we were developing for EE 2 last week, there was one point (I was pretty sleep deprived in my defense) where I lost probably 3 hours over typos, and glaring omissions. Derek Jones (the other Tech Architect at EllisLab) and I would frequently have late night conversations that followed this pattern.

"Blarg, why isn't $this_thing working?"
"paste your code"
"sure, here it is, but you won't find it, I've been...."
"typo line 58"
"but I... ugh..."

I don't care if you've got 1 month or 1 decade under your belt, those types of things just happen sometimes
