Hydration
Type One has one of those water bottles with tidal markings down the side saying things like "3pm: Keep Drinking!!!!!" Type Two prefers hot drinks. Lots of hot drinks. Type Twos are frequently seen on late-afternoon missions to the dishwasher, hands sprouting mugs like an Oktoberfest waitress. Type Ones are frequently seen huffily loading cups into the dishwasher, because Type Two believes in the mystic cleaning powers of The Bench.
Supermarket shopping
We all have to eat, which is a lot of fun for mouths but less exciting for wallets. Type One is a list-driven, meal-planning shopper. They know what's for dinner on Thursday, even if it's the previous Friday. They know what to do with allspice, which is admirable even if the answer is "put it on lamb's fry". Type Twos have no idea what's for dinner on Thursday, even if it's Thursday. They impulse-buy their way through the aisles and get home to an impossible meal of asparagus and cream donuts. Uber Eats relies on Type Twos, but at least they don't have to eat lamb's fry.
Email
Your Type One emailer regularly unsubscribes from marketing lists and replies to emails promptly. They have an email signature that says "Regards", occasionally changing it to "Thanks" when a conversation turns sour. Type Twos have 3467 unread emails but they know most of those are probably from Vistaprint. They know that if you don't reply to an email for two months, you no longer have to. Their email signature is "Cheers", but they have to type it every time and it's only there because it makes them think of wine, which is appropriate as Type Twos are the reason Type Ones drink.
