how did I live without it?

In the gifts my classroom received today, there was a product that I had never used before. I tried it out this afternoon and now I am not sure how I lived without it. The product is a Scotch repositional glue stick. What a wonderful idea. I think it was made for perfectionist like myself. now when I glue something down the slightest bit crooked, I simply peel it up and reposition it. How did I ever live without this?
