Hi, this sounds ish straight forward
Think of three people that you know - a friend, family member, work colleague, child
Why are they different to you - hair colour, height, eyes, personality - are they outgoing, confident, quiet, retiring. Do they have a culture that's different to you, what foods/diet do they enjoy, do they have roots/family in another country, specialise in a particular career path, have an accent, second language ..
Why do you like that part of them - does it interest you, do you admire an ability/skill/way that they have, does it show you how things can be done differently, do you have fun or enjoy their company because they differ from you ..
I hope this helps
