为什么汗水是咸的。。。。。

早上抱着宝宝逗她玩。看她满头大汗的，问她是不是很热。

她突然问：what is the taste of sweat?

"why don't you try to taste?"

她真的用手指粘些汗水放到嘴巴里，说：salty

"do you know why?"

她想了想："there are salt in the sweat"

"why there are salt in the sweat?"

"the salt crawl from my cheeks all the way up to my forehead (and make the sweat salty)"

"how come there are salt on your cheeks, where did they come from?"

"from the raisin box" (她刚吃了些葡萄干）

"what did the salt do on the raisin box?"

"to eat the raisins!!"

"then the salt should be sweet and not salty, raisins are sweet"

编到这，宝宝没话说了，就搬出：it was just imagination, not real.
