What janeainsworth said with bells on. All skills will be useful in some aspect of life and the fact that effort has been made to gain them shows it is important in developing perseverance!
Whether that's wobbling ears for entertainment purposes, whistling for the dog/kids to come inside (my cat also comes to a whistle; I can hear her crashing through the undergrowth running to me at my signal), knowledge of Latin- even better with a smattering of ancient Greek thrown in-means a better understanding of grammar and spelling and so useful for quizzes and crosswords and any sort of sewing skill speaks for itself.
My daughters continually want me to repair things (or get stains out) for them but I have given up showing them how to do it for themselves, so I am now concentrating on passing my skills onto to my 9 year granddaughter instead who soaks up everything like a sponge.
