I like to keep 4 or 5 library books with me all the time when I go places because sometimes I have to wait. Today I took a train to get to where I needed to go and I had library books with me and so I read the whole time while I waited.
My Dad does this too. He usually has a book he carries around and reads when he has time, like maybe when he is on a bus.
The only bad thing is that my purse can’t hold library books but I always keep my wallet in my purse and most of the time also a bug catcher and sometimes binoculars too.
