Task: Question Answering
Input (English): Context: I told my mother I was going to walk from JC Penny to my house , and that I would call her again when I was there , to ensure that I was alive and that someone was looking out of me . walking back was pretty uneventful , except that for about five minutes the wind was blowing directly into my face , and I did n't have a scarf . thank goodness I had proper gloves , not the knit kind but the leather kind , and my jacket was waterproof . 
Question: why did I have a waterproof jacket ?
Output (English): to defend against the rain and tough weather.
