Ok, i get the felling that there is some snide personal comments brewing, so please, if agitated by a post, please do not respond with an insult. Thank you.
For me, I spent several years with only one parent. When i was younger, my dad left for 3 years to work on a project (Universal Studios Japan) and i was left with my mother and sister. I grew up just like every other kid and saw very little of my father. Now, my parents are divorced and I live with my father. I still live the same life and now see very little of my mother. (I don't stay with my mother because a few years ago she suffered some brain damage in a car accident and now isn't really suited to take care of us, though we still love her very much and she loves us, she's just a bit nutty now.)
Only very recently (within the last 3 months) have i really had 2 parental figures (my dad is getting married again). I was raised fine, as was my sister. She is going to graduate 3rd out of 850 students, got into Georgetown university with an amazing scholarship. I have Straight A's, am often co-teaching my Biology and Geometry class and we are both sociable. I know many people in my school in similar situations. One girl lost her father when she was 5. She has a 4.48 GPA and is going to Yale. Another is a boy who lost his mother to brain cancer about 7 years ago and he has straight A's and is an amazing sports player. These are just a few examples showing that one parent can still raise their kid quite well without them becoming "girly" or a "tomboy". Just a few personal examples.
