What is embarrassing? – When somebody wants to do something he knows he shouldn't. Look at the beggars: we always feel a little embarrassed by them, because they ask undeservedly. We can't either give or not give them. And trust me, they are embarrassed too. That's what so uneasy in those situations.
I recognize the confidence in me when a beggar approaches me. He squirms relieved as I reach into my pocket. I start with low, confident voice to deal with him graciously; but when I feel the block coming, I glance aside. While I stutter in the outside, the recognition pierces into me without mercy; –
I am the beggar.
