It is dang near impossible to explain the "Expat Hoarder Mentality" to someone who hasn't lived abroad.
Never, ever take for granted the ability to go into a grocery store and buy exactly what you want, when you want it. That's a luxury I didn't quite understand until I moved abroad.
For instance, I just got over a horrible bout with the flu. Actually, that name doesn't do justice. Let's be more specific, and refer to it as: Satan's Sick Way of Making You Wish You Were Dead Tummy Bug. Anyhoo, as I was clawing my way out of the trenches today, I would've done unmentionable things for a bottle of ginger ale. Now, my stomach doesn't tolerate bubbly drinks anymore, but I would've been willing to risk it for 1/4 cup of some blessed, *real* ginger ale. But no. Because I live in Korea.
This is why I have found a deeper appreciation for the convenience of American shopping. Want some spaghetti squash? Go get it! Need some Crystal Light? Here, take 20! Have a hankerin' for some peanut butter cups? Come on over, we've got plenty.
Say a little prayer. Thank God for American grocery stores, friends.
