What is this wet stuff?

It’s raining really hard. I can’t even remember the last time I saw it rain this hard. There are huge puddles all over the place. I must say that driving in the rain in my mom’s car is alot easier than in mine. The wipers work, and it doesn’t leak and it isn’t as slippery. I found a raincoat in the hall closet, and I put it on. I think it’s my grandmother’s but it was pretty nice. A long heather purple coat with buttons and a tie. That’s about the only nice thing about rain.
