Fun says, "Air Supply's I'll Never Get Enough of You, 'And if I never have another love, well at least I had last night.'"

Appreciate what you've got.
Don't complain.
For you are already given what you really need.
Be happy with it.

If you appreciate it now,
At least in the future,
You won't feel regret when you lose it.

So, I really appreciate the little time we've spent together.
I will be there for you whenever you need me (provided that I'm informed...:P).
And if I lose you,
At least we were happy together once before...
