How to keep aged people happy??

First of all for the matter of fact they are aged people and what comes in their mind is not in their control, its the age which speaks.

They have huge insecurities abt being left out alone of every small things, modern lang me people say it as FOMO (fear of missing out), which is very common these days

They want to be involved in every small things which is not feasible but the younger members of the family should see to it that they keep them informed  abt every small updates abt whats going around. Also try showing them every non routine thing you purchased.

They feel emotional abt very small things and they dont have anyone to whom they can talk to,( unlike us, we have our frnds, partners, parents and many more people on whom we remove our anger and emotions),  and it will come out in a bad way, so be ready for it and don't take it to your heart.

They are aged and communication from their side is little difficult they feel bad abt communicating their requirements to us, so we cannot expect them to ask us questions and then we answer it, we should try to keep them updated and keep fulfilling what they want.

They understand us more than anyone else can but sometimes they break down and then its not in their control what they speak, so try ignoring that phase.

We are not under any compulsion to follow each and every idea they give , because what they suggest may not be practically possible, but we should also not say a straight no to them and just say that we will consider.

They have given their life to bring us where we are, so we need to understand this phase of their life and co-operate with them. And about mother-in-law, someone is taking care of your mother, so its our responsibility to take care of them.

They feel terrible when the younger members of the family face problems because of them, its not easy for them too.

And how lonely they are we all have no idea at all, how they wish to die every single day we have no idea, they not enjoying their old age either, but as we all know its in no ones control. 

And always remember we will be the worst version of what our elders are, when we get that old!!
