I don't have the same friends that I did growing up. Those grade school friends are all grown up and our lives have moved on. Same with "Well be friends forever" from high school (at least that's what's written in my year book)
As we change so do our tastes, activities and friends and that's all OK.
When I first moved to Florida I met some people who made the change easy. Only three of those people are still real friends: people I keep in contact and see as well as do stuff with and that's OK
