Well done for enduring such an experience with strength and dignity!
Its almost like you were able to apply the Convention title and were "courageous" hehe.
I think it was nice that you went for your father's sake. After all, that is what families should do - support one another's big events in life. So I wonder would he now attend some event of accomplishment in YOUR life? perhaps some work awards night, or community awards night?? Would he afford you the same support to something you hold dear?
