Generally speaking, I think the relationship between a child and parent can never be perfect, however people may assume. Behind closed doors, its always a different story. Which makes me think about my next point. Does your parents ever act differently when your friends are around? I mean, isn't that the more perfect time to ask for something.(Money, Car keys or hand in marriage--i'm playing) Although its very true. I know this because i'm a single child and have my little ways when i want to get something, even though i'm naturally spoiled. (when I was younger) I know its not easy being a parent, nor easy to put up with the daily stress from work or bills. Yet that is still no excuse to be good parents. No sorry, excellent parents. But all in all, when everything hits the fan, parents will just never understand.
You like how i made that last sentence rhyme huh? LOL
