You can view things as transactions or a chance to build a lasting relationship. It's your choice.
Went to my 10 year college reunion on Saturday night and I'm really glad I did.
It's great to have these periodic check-ins with people who affected (to varying degrees) the person I have become.
It's also interesting to see how different lives are playing out. Some people...well, they are doing exactly what I thought they would be doing. Others, a bit less so, and others, well, their lives are nowhere where I'd thought they be. This is great, because it forces me to think about judging people too early.
I was very glad to see many of these folks. It occured to me that the people who do take the time to come to reunions are those who view college as a relationship, not as a transaction, and frankly, we're all better off that way. Good for us, that we valued our time there and we made friends, developed into the people we are becoming, and continue to learn from each other.
