Mar Bar Ravina & I
When I feel that another person is looking at me askance it is often a sign that it I am the one projecting these feelings onto this person. Yet, there are times when my perception is completely accurate and the person is looking at me and not seeing me, only my big red beard and yarmulke.
When I notice these disparaging looks, I fight against my innate nature and try return them with a smile or a friendly greeting. And when I daven, these people come to mind when I finish the Amida and say the last line of Elokai Netzor.
