Well it will- without that reality- check you may well have continued to do it!
I'm 27. I don't know anyone who has lost a license due to DUI- due to speeding/other infractions building up, yes, I know three people. I'm from Perth, Australia and our limit is 0.05, which is lower than at least some US states I have heard of. Driving under the influence is just plain stupid and age is absolutely no excuse.
Jenelle is smart, I believe, but obviously has some self esteem and mental health issues. I feel really sad when I see her searching for a relationship to fill something inside herself. I can't believe she's ever had a positive male role model in her life. Barbara obviously does her best but hasn't raised Jenelle well. Her whole story just makes me sad.
