Nice question "marli" let me share my personal experience with you !
One day .. I was coming back from middle school tht time , & I had a very bad mark, my cell phone & my money were stolen (so I couldn't take the bus) & it was raining tht day ... I remember: tht I had a horribe headache .. It was 6 PM & no one outside because of the cold wether, In tht silence; I was sitting in some corner like a statue when the picture of my grand-mum who passed away turned in my mind .. actually I start crying for about 20min??!! then I saw a monster(hehe) .. a very old man with one left leg & one right hand walking with crutches :-((((( .. he was like a skeleton .. looked like a beggar because of it's cloths .. when he was near to me I felt like I'm dying :-p .. he looked at me in my eyes, smiled & went!! how some (almost) dead person like him can smile & I'm waiting death here ? he really taught me tht we hav to fight to stay alive & not just giving up in the first exam !!
-It's a true story & I'll never ever forget tht lesson :-)
