Yes Indigo, they do. I am a strong believer of people having roles to play in our lives and leaving or growing apart when their roles have been well executed.
It hurts sometimes but it is what it is. Everyone moves on and life keeps serving. Bask in the good memories, whenever they stroll by enjoy the conversations or little chit chat with them and know that it can't be the same again. Thank you for always sharing how you feel and giving perspectives.
