Happy Campers Fork In The Road Lyrics

A time not long ago
friends would come and go
but one or two
would seem to stick around
Hangin' out like everyday
seems they'll never go away
best freinds are forever
they'll always be down
it seems we're at the start
of when things fall apart
it won't be long before we go our seperate ways
You've changed
[ From: http://www.elyrics.net/read/h/happy-campers-lyrics/fork-in-the-road-lyrics.html]
and so have I
think I know the reasons why
but I can't take us back to the good ol' days
How could you change so much?
You changed so drastically
It wasn't long ago
that you agreed with me
You wanted to have fun
to live life was to play
what could've happened to  make those feelings go away?
