Good Karma?

I know that I have been given the chance to help a lot of people and have either missed the chance or didn't even notice it.  There have been 3 times though in the last 6 years that really stick out to me. 
1st- This was 6 years ago- or so- and I was on my way to work driving down University Ave.  I wasn't in any hurry and as I drove up to the intersection with Provo High one on corner (Bulldog blvd?) I noticed a man in a suit running across the street waving his arms.  Then I noticed a bus driving away.  The rest of the way to work I thought- I should have turned around and asked him if he wanted a ride.  Why didn't I ask him that?
2nd- I had been dealing with two sick boys at home- this was last Christmas- and had gotten Chase to stay at home while I went to Target.  I felt like I hadn't been out of the house for ever and was still on edge from boys crying all day for several days.  As I walked down an aisle there was a mom with a 3 or 4 year old boy who was crying.  The mom kept telling him to stop crying and he kept saying "Mom, I need a Kleenex!!" She told him she didn't have one.  I walked by, and thought to myself- I think I have a tissue.  I could give it to her.  But I just kept walking.  I have always felt so bad about that as I have been there so many times.
3rd- Yesterday as I was driving home from mailing a package I saw a collage-age girl running with a big art portfolio.  She was over by the intramural fields, and after noticing it was 2:55 I thought, there is no way this girl is going to make it.  So I turned around and asked her if she wanted a ride.  She got in and told me that she had taken all her other finales so that she could work on her art final.  She worked for 24 hours and it still wasn't done but she was on her way to class to drop it off.  As she got out she looked at me and said- you just made my day.  Thank you so much.

Then we drove to the Thanksgiving Point lights and on the way home got pulled over for speeding.  The officer checked Chase's stuff and told him he was going to give him a warning.  Good karma?  :)
