I find that from growing up around my grandparents I was able to receive some good habits, but also some learned negative habits. One set of grandparents was very moral and supportive. The other set of grandparents had a very dysfunctional relationship, and unhealthy habits such as over-eating, smoking cigarettes, sleeping in all day, being bossy and demanding. My boyfriend grew up with grandparents and extended family, and I envy him the freedom of being un-obligated to attend regular family gatherings, and not worrying about Christmas, etc.
I have ethical problems with the idea of bringing kids into this world. I have struggled very hard upon entering adulthood, and gone through depression, and uninspiration, and I would hate to bring kids into this world and tell them that they will always be happy and then have their dreams be destroyed.
At the same time, I was raised in a very religious home, and made to be unprepared for the world we actually lived in. Naivety made me an easy target, and if I did have kids I would try to prepare them for the realities of the world instead of sugar coating everything for them and not telling them the truth- like my parents did.
