As a brother you do not want to and you cannot tell your sister that he/she has a cancer. As a brother I would never be ready for all side effects and for everything what we went and what we are going through.

You are never ready for that...

We do not understand what other parents of children with similar diagnoses are going through.

We pass fundraisers on the street, shouting and banging with buckets of coins but we do not understand until it is touching us, or it is our own child...

Everything else is meaningless in that moment. Time and date does not exist anymore. There are no days of the week. There are no material goods. And the money have only value of the health for ever...
