Things I have learned:

Funerals tend to put things in perspective.

I have observed:

That people may not be all you think they are.  Chances are, you get to see a tiny sliver of someone's life, and don't have the full picture.  Don't judge too harshly.

There aren't enough second chances.  If you want to say, "I love you," or "I'm sorry," or anything else; seize the day.

You have an impact, as a person, that you may not know you have.  Everything you say and do leaves an imprint, bad or good, on someone else.  Do your best.  Be your best.  The consequences are far reaching.

Conversely, a person shouldn't be measured by what they do for a living.  Or even their hobbies, but WHO they are.

Think about the people that you call relatives.  Do you know them?  Really know them?  When was the last time you made an effort to?

Go tell someone you love them.  Pick up the phone, or cross the room, and tell them.
