Our parental figures are always looking out for us even in the most irregular situations. But even so, you should always be able to help them. Even if it's in the smallest way. They love you, and love is one of the most amazing things in the world that I find very fascinating. Love can be shown in any way. In that case, Yes. You can and will always be able to repay your parents for everything they did for you. Even if it is beyond the grave. Love Is very strong so you should NEVER restrict it. <3
