Single-Parent Family and Legal Marrying Age

I read some Chinese magazines in the library of Kumamoto University these days, and there are some interesting topics written on the one called "Reader" that I'd like to share and talk about with all you guys.

The fist topic is "Single-Parent Family".
I have known some friends who are in single-parent families and I am also in the same situation. For me, it's not a problem to own a happy life without a father, just like other normal families. It was grieved when my father passed away at my ten-year-old age, but since my mother was such a brave and positive person, I never felt myself different from other ones and we two did spend substantial and happy life. But if there goes any regret, then I think the biggest one is that chirldren from single-parent family are usually lacking in love from both the parents, which can be called "balanced love".
My mother gives me a lot of freedom so that I can do whatever I like as long as I don't hurt myself and the society. But sometimes, I would like to imagine if I had a father, how will life be like. Is that more fun? Or just because of father's stricness I would lose some happy time.
What I want to ask is that do you guys think that chirldren from single-parent families can be different from ohters? I mean in psychology or behavior. And if you are not the one coming from a single-parent family, do you think you are lucky and be satisfied with living with your parents?

Let's go to the second topic now. It's called "Legal Marrying Age".
It's such an interesting thing to compare the legal marring age in diffrent countries. What I have already known is that in Japan, it's 16 for women and 18 for men. In China, 20 for women and 22 for men. And in Thailand, 15 for women and 16 for men, which amazed me a lot. I'm not clear about America and oher western countries.
Based on the dates, you can see that the legal marrying age in Japan and Thailand is when you are in minority, which is interesting because some people may say "How could this happen!? They are just chirldren!"
So my questions are:
1. Do you have any problems with your own county's legal marriying age? If does, do you think it too early or too late?
2. When would you like to get married?
3.If you are faced with an international relationship, do you think the "legal marrying age" could be an obstacle between you and you girlfriends/boyfriends?

Thank you.
