Thats a lovely story, and a fine thing to do.
No matter how small or trivial it may seem, to offer help to a stranger (or anyone) is immensely satisfying, for both parties.
Although help is not always well received, I have encountered people who look at me like I`m some kind of leper for offering help, but nevertheless, I
know my actions were of service to another individual so karmas on my side at least.
I always wish I could do much more to assist others though, and although I`m a single parent and by definition my entire week is based upon service to
others, I still find that I serve myself at times where there is evidently a situation that could be devoted to making another persons day more
pleasant.
In a bid to compensate, when I meditate, I ask to find the way to be much more of service to others, and it does work. Since I began trying this out,
Iv`e had situations presented to me that require me to door say something to make another person`s day easier or to put their mind at rest, and when
it happens I know it is answer to meditation, it kind of shines from the moment.
S&F for you mate.
Keep looking for the Karmic path.
Namaste`
