For some, life lasts 100 years. But, even that's rare because, for most, it's about 80. Some die at 70, and others at 60. Even 50 and 40. Hell, 30, 20, even 10! No, even at a couple months old.
My point is, life is so short! It ends at the blink of an eye. 80 years sounds like a long time, but it really isn't.
And, not everyone dies from old age. You're considered lucky if you do, in some parts of the world.
You never know when that time comes, for you and your loved ones.
Therefore, cherish those moments: the walks to the park, the family dinners, and even the little arguments that remind you your family is all you have.
Because, your family IS all you have, in the end.
