The following Girl Scouts Motto has been submitted by many people in varying forms, so I've just placed the three most popular versions on:
1) "Make new friends and keep the old, one is silver and the other gold"
2) "Make new friends, both young and old, one in Silver, the other Gold."
3) "Make new friends but keep the old, some are silver and others are Gold"
4)"I have a hand, and you have another; put them together and we have each other."
