What I carry with me

I left my poncho rain coat thing at home. I don't think I've actually had it on me since the semester started, which is bad because odds are it will eventually rain and I won't have it. There was once a time when the rain wouldn't bother me. In those days i didn't leave my rain coat poncho thing at home because I forgot it, but because I didn't need it. Back then my rain coat poncho thing was an umbrella. I let one of my friends borrow it on a rainy day and he lost it. I've considered buying a new umbrella, but I think what I have now works well. I don't think anyone will want to borrow a raincoat poncho thing.
