obvious promotion to your services aside...i think you have a point.
sending them to old folks home might be easy, but it also creates stress in the parents. they will feel abandoned, loss of hope, and just stay idle waiting for death. yes of course the children will come by but inbetween that visits he/she will feel lonely. better just have hired helper/nurse in house. even if you're busy working at least you know she's near.

most people now hire maid also. provided the parents is healthy and able lah. not stroke or on kidney dialysis machine/life support one
