A little over a decade ago a group of friends and I started ending every lunch date or phone conversation by saying "I love you". We never got together and agreed to do it, but we were all raw from watching the endless news loop of planes crashing and buildings falling to the ground. Thankfully, the habit stuck.
I never understood people who think that the phrase "I love you" can be overused, that it somehow turns meaningless when it's heard too much. Of course, I don't believe in saying it when you don't mean it, but neither do I think anyone ever went to their deathbed regretting that they told the precious people in their lives that they were loved too much.
Every time I hear those words said to me in earnest, a little part of me lights up. Every time I say them, I feel a little lighter. No doubt, I will have many regrets in my life, but it's nice to know that being too stingy with that particular phrase won't be one of them.
