This moment of your life your parents don't need to make them young again. They need no they need you to notice that they are getting older the difficult part is it doesn't matter.
It doesn't happen dramatically so it happens quietly so at that moment one day they stopped doing something they used to do so they are still becoming repetitive they move slower they stay one place they think about things have happened.
They have grown, their bones are weak and grey hairs have already grown up. You have to focus on being in your life.nAnd forget that you have spent so much years putting just on hold.
Don't wait till your absence to make ordinary memories valuable. Call them, cherish them, visit them, zoom to them. And there will be a last time for things that you might not realise, might be a last time.
Connect with your parents and also share love with them because you might not meet them again.
