I've discovered that BF, like me, can't talk about romance without getting embarrassed and then covering it up with a joke. Like when we watched the sunset, he recited a flowery love poem (that he'd memorized years ago for a class) which caused me to cry with laughter.
The boat ride from Crete was another ridiculous moment. For three hours, we listened to dozens of passengers retch with seasickness. Luckily our group was fine, but vomit noises was not the ideal soundtrack.
Things with BF are fine, given the rigors of spending ten days together. I had one major moment of crankiness, and BF was sweet about it, when he had every right to be annoyed at my random moodiness. Traveling together overseas is definitely a good way to figure out if you can deal with someone... I've lost friends over it!
