Just listen to any of the recordings to family members by those people trapped in the Twin Towers on 9/11.
It can break, or possibly make, your heart!
The one, major theme, that these people shared, is that they told those they called, that they loved them.
How long can you avoid telling those close to you that you love them, or are grateful to them? or that you apologize? or that you forgive them?
If you knew you were going to die at any minute, would you regret the days you held back sharing your love?
