Answer:
1. Yes, if there is no any choices, then I am willing to sacrifice myself.
2. There is, it's because I had my personal experiences about it. I choose to sacrifice my own will just for my parents even thou I'm still in need too.
3. I believe that to show love is to show respect, that is why I don't tell anyone that I love them, instead I let them show my love towards them by the word "respect". Respecting my parents, fellowmen, country and as to God in heaven is the best way to show your love.
