Bhai, it's 💯 percent true that life is uncertain. Kab ki mode par zindagi googly de de ye nahi bata sakte.
Live the life to the fullest. Make sure that you pass on her story and cheer for all the good memories. Life has ups and downs and you that too. Celebrate her life. Remember the good things, forgive and forget the bad ones. And move on brother.
Om Shanti
