envelope

A 5 yr old had finished up his Klimt inspired wind sock and was coloring a free draw. I looked over to see him licking the paper. I watched him for a few more seconds and he was running the edge of the folded paper across his tongue - this was really strange to me so I had to ask what he was doing. He said he was making an envelope, I told him to just use a glue stick that licking it wouldn't make it stick. He then told me " it works with mail!" HeHe
