This sort of thing happens.
My story is is similar to mnemosyne's - people move away, lives change and over time you have less and less in common. I don't know if it's necessarily a bad thing...it's a part of life and rare to find friends that can grow and change at the same pace in the same direction. And as people have less and less in common it's harder for people to get along (I don't think this is a hard and fast rule - it's just my personal experience with friends I've had) |
