Ice Rain?

Something weird happend in town today. When driving back home from Pang's birthday celebration at jusco around 3pm, suddenly the sky turned dark and no longer it rain. I was in the car when raining, suddenly something falls on the car, something hard, it's like someone throwing stones at your car. Damn, i was like so pissed and curios who the baboon dare to throw stones at my car. So i looked around while driving, i saw something very funny i saw stones falling from the sky together with the rain drops. My brain is full of question marks. The weather really bad, rain heavily, wind blows strongly. By the time i reached home, i told my parents that just now the rain was so weird the rain drops with stones. *haha* They replied, it's ice not stone. Weird huh?
