You can't be homesick, if you always feel at home.
Lexington vs. Amman. I'm not sure two places could be more different, yet I gladly call both of them home.
Similarities: hospitable family and friends, food delivery, most people from either place don't really know where the other place is, cookouts or barbecues are always a success, the weather temperature is pretty similar throughout the year (although humidity and precipitation differs exponentially), agreement that Coke tastes better in a glass bottle (although in Amman you order Coke as cola and Pepsi as Pepsi).
Differences: In Lexington we walk around barefoot but in Amman sometimes sandals even seem questionable; In Lexington there are BBQ restaurants on every corner, but in Amman there are falafel stands; In Lexington you may see one taxi once a week, but in Amman you will see a taxi before any other mode of transportation; Lexington doesn't have any malls, but Amman has many; in Lexington you munch on carrots with a little hummus if you want to be healthy or fancy or different but in Amman we eat hummus by the breadfuls when we are poor or as a side dish at basically every meal breakfast. lunch, and dinner; in Lexington we drink iced sweet tea, but in Amman that's a specialtea (pun intended); in Lexington you see cows grazing, but in Amman you see camels (they are also available for giving rides at any moment, just ask), in Lexington the average glass size is anywhere from 21 to 32 oz, but in Amman it's about 8 oz, also refills aren't really a thing in Amman.
By the way, Happy Hummus Day.
