If you dont attach to people then you might not suffer, but you would also never feel all the wonderful emotions like joy and contentment
True, but we are on a roller coaster if we are are overly attached to impermanent things (people for instance). Loved one change, grow from a baby to adulthood, get old, move away, get sick, they die. I think that True joy & contentment has to come from within, not from external things or people. I have started working on myself - I have long, long way to go.
