If you get married or start dating in the new country, it's worth being aware of how much more culture shock your partner is likely to experience when visiting your country of origin.
I kind of made this mistake after leaving my home country for many years, getting married, and moving home(-ish) with my spouse. I needed time to readjust to the surroundings, but it was mostly digging up old memories. (Also, it wasn't exactly where I came from, so some things were different.) I mistakenly fooled myself into assuming that things that I remembered would be natural for my spouse, which was obviously stupid.
I was dumb. Don't be dumb.
To be fair, Avril Lavigne signed away the movie rights to Sk8ter Boi to Paramount in 2003, and we still don't have that movie.
Selling IP rights into another medium is not the same as a guarantee that it will be developed (though it is a first step).
