I am sure that you will also see the truth like me in the later years once they are established with their own families. Life just works out like that and it might sound cruel, but I always told them that once they are finished with school, that's it, they must go and make their own lives.
Two of them continued to study at university and I only paid their registration fees.
They had to find part time work to pay their own courses and exam fees. Best move I ever made, as today they are proud of their own accomplishments!

Now when the time comes for me to depart this life, I can go in peace, knowing that they are quite capable of looking after themselves.

Cheers and thank you!
