Great gift to parents is to stay with them always and that is the most deserving gift they wished to. 

It's not exactly about staying with the parents. It's all about keeping a tab on their lives, their old age problems etc and lending the helping hand to them at the time of necessity.the important aspect is to let the parents know that there are their children to care and love them,

Absolutely, by staying with parents all sorts of problems if exists for them would not be there,

I do not stay with my parents. But I look after their needs as they stay in thesame locality . In fact my parents do not want any assistance from me as they want to lead an independent life. Still I do what I'm supposed to do.
