Right before 16 Kennedy Airport in New York, my grandma 17 me of the behavior of the native mosquitoes around the 18 like me. She said, "There's an old saying—the 19 you stay away from the motherland, the sweeter your blood 20 to the mosquitoes. " Not 21 it, I replied, "Grandma, that's just an old wives' tale!" Well, less than a week 22 my arrival in Manila, I was already carpeted with a 23 of mosquito bites. I took many measures to keep myself from being 24 , but they all proved useless. Late one 25 in my cousin's home, I couldn't bear the 26 of the bites. Hoping to find some comfort, I 27 my cousin, who was sleeping peacefully in the bed next to mine.
