When I was a little girl my favorite book was about a little boy and girl that got into a fight over their toys. If I recall correctly the little boy knocked over the little girls sandcastle. Anyway, they ended up being friends again and said something like they are the stick like stickiest glue friends. This was me and my moms saying. I would love to find it for Christmas for her and cannot remember the title. I was born in 1981 so it has to at least be from the 80s. Thank you!
