Becoming comfortable with your own sweat, in what seems to be unbelievable amounts.
How to get by with less than you think you need.
Pants are actually trousers.
How to laugh harder than you have in ages (play soccer with 15 Kenyan coworkers some barefoot, from at least 3 different tribes, on a "field that is half dead grass/half dirt and on a hill with many holes in it, in the blistering sun. note to self, always have a Masai on your defense).
How to speak up for what you need even if it's not convenient for others- this one will take time.
Learning local names, because honestly people sometimes don't realize you're talking to them if you use their baptismal name. Favorites so far include Waweru, Wangui, Wambui, Karanja and Shiro.
How to compile a homemade Swahili/English dictionary with a 10 year old while watching music videos on TV and suddenly becoming nostalgic about songs that I once hated hearing on the radio...funny how that happens.

How no matter HOW dark you die your hair, if you're white to begin with, Africans will still spot you like a sore thumb.
The way dirt can cleverly serve as a "dry shampoo" by default.
Playing the game of, "what might these people be saying to one another??", this game is more fun than i originally thought.
Not panicking with the insane traffic, cows crossing the street in herds and people riding bikes with cargo piled above their head in the back, other people pulling large wooden carts, moto drivers, matatus etc. etc. (all while driving on the left)Somehow in this chaos there miraculously isn't a collision every 5 minutes.
"Bis-kwits" means cookies (biscuits) and for the longest time I thought everyone was referring to "Bisquick" and was puzzled by how into pancakes these people are. ha!
If case of any confusion, flavor your food with salt and pili pili (red pepper).
How guacamole, when made on another continent far from home, tastes 100 times more amazing than it ever did before.

and the list will be endless, i'm sure.
