I lost my best friend back in 2007.Still remember the good old school days...our mischievous activities and then someday everything changed and we both had to move on.
It happens often. I am sorry you have gone through that. I think as worry free kids we often find it easy to bond, though kids with a lot to worry about, also bond. I think the latter is the stronger bond. I know for my own experience life got in both of our ways, and it just pushed us down different paths😢.
