Protips:

• walk everywhere fast. About as fast as if you don’t get to the toilet immediately, there will be a serious accident
• when someone asks ‘How are you?’ or how you’re going, the first words out of your mouth are “Busy” or “Flat out!”. Adding anything after that is optional.
• Bonus points for always being the one to initiate the break off in a conversation. Look at watch, “Well, I gotta run, XYZ is due…”
• The immaculate hat-trick is combining all three without breaking stride as you blast last someone
