Maybe, some people enter ur life in orfer to creat wonderful memories before they leave, it's hard to come to terms with that whether thay walk away alive or dead. The only thing we can do is keeping that person alive in ur memories as long as u can.
That's someone doesn't need to always please u like a gf or bf but they can make u happy.
That's someone doesn't need to cherish u like parents, but they can give u warmth & they r always ready 2 protect u.
That's someone doesn't need to make us laugh at all times like friends, but they can make u smile.
That's someone who u won't go to hysterics when thay leave, but they will always be in ur memories forever.
