Well on one hand -- I've love to have my brother's commercial airline pilot career! (But that would take something BIG away from him, so I wouldn't do that.) Failing that, it'd have to be a family keepsake of my choosing (after poring over their collection as compared to mine) -- might be an old photograph, sentimental object, etc -- something that belonged to my father or my grandmother maybe.
How will you celebrate New Year's Eve this year?
