Well, one thing is certain -- you won't find each other boring! You'll definitely feel an attraction to this friend, and maybe even a magnetic pull based on your differing personalities that is compelling enough to surprise both of you. Your ideals and values may not align perfectly, and the differences will be apparent from the get-go.
The resulting tension could lead to misunderstandings and other difficulties; if so, the best way to deal with it will be to talk it out as best you can and see if you can understand at least where your pal is coming from. But it's more likely that this inherent tension between you will make you actively aware of one another and interested in where you're both coming from. In fact, you'll be interested in each other for your very differences, as each of you will instinctively recognize that this is no ordinary friendship that you share.
