You two probably just won't get each other's flashes of brilliance. You've got quite a generation gap going on. The qualities about you that make each of you an individual, a genius in your own right, will be lost on this person -- and that will go both ways.
The funny things that each of you will say, the great ideas, the creative approaches to problem-solving, will be met with misunderstanding at best, or even irritation. You'll just drive each other crazy if you're too critical of each other's ideas without even really understanding them. Instead, why not take a different tack? When your friend says something that you don't get, just go with it. You might find that you end up someplace that you never expected -- someplace good. If you're thrown off track temporarily, what's the big deal? Working this kind of issue through will be a great way for both of you to loosen up and enjoy each other a little more, as well as learn to understand others of vastly different ages.
