I think one of my favourite things in the whole entire world is families that look alike. You know those families where both parents and all the children have the same face? Actually, I'm happy when just the children look exactly the same.
I wish I looked exactly like my brother (well, a female version of him). It would probably improve my life by about 5%. PLUS, my brother's pretty buff.
Other favourite things...? Or um, if you look exactly like your mum/brother/other family member PLEASE show me. It would make me ever so happy.
