I was one of that kind and i learned from that lesson,we sacrifice ourself here for the sake of our love ones back home,we saw them happy celebrating that special seasons although we are just looking at them on the monitor,its nice feeling as well that even on that way we shared thier joy and lessen the sadness and loneliness we felt...what i learned is that We have also to think of ourself,because we are working here for them,whatever happen to us,no family here,no one will care if something happen and its a shame to ask or lend somebody here whom not related to us...i always believe that saying goes...KEEP A PENNY FOR A RAINY DAYS...it really applies.
