maybe drinking cold water does give you a sore throat after all

Rwandans have many superstitions. One of the many is that drinking cold water gives you a sore throat. This seems so absurd to me considering it is hot outside, and why you could possibly want room temperature water EVER is beyond me. All summer I have been putting a water bottle about 1/4 of the way filled in the freezer and then bringing it to work. The staff at the office incredulously watches me drinking it like I am crazy. Everyday they warn me that drinking cold water is painful, its bad for your throat, it's disgusting. Naturally, I have ignored all of these comments.
And now I am laying in bed with a very sore throat.
