Proverb from Morocco

I listened to the radio today and Karima El-Mahrough alias "Ruby", when asked about the sex scandal with Italian Premier Silvio Berlusconi, answered something like: الجمل دائما يرى سنام شقيقه ولكنه لم بلده, that means: "The camel always sees the hump of his brother but never his own." "That", she said, "is a proverb from my home country Morocco!"
