I don't know what it is, psychologically, that builds that bond so tight, but I know it's just as true for me as it is for others. The funny thing is we don't agree on everything, but we agree on most everything. How crazy is it to meet someone in your teens who enjoys all the same stuff you do, thinks similarly, and with whom you build a solid connection, so solid that decades later you can pick up like nothing ever separated you two? I love it! I would think there are only so many special people out there that match me that well, but it can't be that few if so many people are able to find someone like that and have a similar relationship...it's mind blowing to me...
