I needed to give a certain person money but I usually only see him on Shabbos. Out of nowhere he shows up at mikva at the exact time when I was there. But - I didn't have the money to give him.
Too bad.
Then - I'm not making this up - out of the blue someone walks in and hands me an envelope filled with money.
I handed the money I needed to give this man over and went on my happy way [he seemed quite pleased as well:-)].
When you want to do good and you know that Hashem is with you everywhere - you will see nissim!!!
