Mothers Against Drunk Driving (MADD) is a very visible group whose main focus is to educate the public about the harm caused by drunk drivers. A study was recently done that emphasized the problem we all face with drinking and driving. Five hundred accidents that occurred on a Saturday night were analyzed. Two items noted were the number of vehicles involved and whether alcohol played a role in the accident. The numbers are shown below:

When you like a flower, you just pluck it out.
But when you love a flower, you water it daily.
The one who understands this, understands life.

- That's the difference between I like you and I love you.

I think MADD is quite a nice initiative and more mothers should join and educate their children what havoc a DUI charge can have in their life. My friend works with a DUI attorney Los Angeles and often tell me how DUI destroy people’s life.
