While I love to help, just somedays, only a few days in a month on average, I don't want company in my car. I want to drive alone. Stop anywhere at whim, shop anywhere at leisure, take a detour if I so wish...I might have to pick a friend mid-way, I might want to meet my husband somewhere and we would be going off for a drive...I simply may have other plans which I don't want anyone to know.
If you are there with me, I am obliged to keep you posted, obliged not to take a detour and feel apologetic if I have to go shopping and hence request you to get down several stops ahead of your desired stop!
Well, I am just building on the good karma.
I am just saving the earth by helping in having one less vehicle on the road.
