many of the participants here tell me what can we go back to? we have been denouncing the mubarak regime for three weeks now and our faces all over tv. we will be targeted. there is no choice. this is our chance and we're not looking back. >> sharif, tell us about the people who are protesting. do they go home and eat dinner? i mean, are they destitute? are they -- do they just have the shirts on their backs? how do they function? what is it like day to day in egypt from what you can see how they're functioning? >> the protesters cut across class lines, cut across religious lines, cut across political lines. so some protesters spend a few days here then will go home and regroup and then come back. but there's always the presence of many thousands here. it's grown from just a couple tents to a virtual tent city with pathways and different kinds of encampments and food now and, you know,ou never go hungry.
