The Missing Letters

Once there was a land which no one had ever explored. In that land there were elves who wrapped Christmas presents.There were about 100 of them all working at once.Then one day all of the letters went missing! They needed the letters so they knew what the children wanted.They searched and searched for the letters but they never found them.Then a couple of days later one of the elves said he had founed 30 letters in the bin but they turned out to be old ones. As far as I know they are still looking for them now.
