Old.

Sometimes we just wanted to be remembered, not always, but maybe during happy moments. But, things won't be as what you could have wished for always. As time passes, new people come, old people say farewell.

So, never take things too deep in a relationship, be it a friendship or even family bonding. No one could commit to a single person the whole life. Later, you may be forgotten and that is reality.

Appreciate what's in front of you.
Don't look back.
