Ranger Steve has got it right, there are so many unhappy people out there ignored by the very people who are supposed to love them the most, you see it all around you, everywhere you go. I think it's also the reason for a lot of the bad behaviour by teens and children, you see them in the street or on buses acting really loud, swearing and cursing. All they are subconsciously saying is "Look at me, listen to me, for gods sake someone please take notice of me!"
All anyone really needs is LOVE not material possesions.
