Who would I like to punch in the face this week?
Everybody who stops by the prototype I'm working on while my head is stuck in the engine compartment and my ass is hanging out in the air and asks "Hey! Is this the new prototype?".
No. No it's a waste bin and I've dropped my phone in it. Come help me look.
I just take it as granted that people understand that if they can't see my head, they know that I am currently busy. So please fuck off and take your idle chit-chat to someone who gives a shit.
