Do you think society puts too much pressure on people to be in relationships and/or have children? Do you think this ostracizes people who would be perfectly content to remain single and/or child-free? Is this pressure worse around the holidays?
Relationships, probably. Children, not so much these days. Actually, there's different GROUPS that exert different pressures; for instance, my wife and I belonged to an anime fan circle and a number of those were essentially offended when we dared have a child. Others in the group were fascinated by the baby, but it was actually possible to wander through the different groups of people I knew and see clear divisions of reaction. There were groups that didn't like young children, and thought people having kids (especially people they knew) were wasting time and energy and generally being stupid. There were other groups who felt children were wonderful. If I were to average out society as a whole, I'd say no, there's no pressure on either side for or against children. However, you are very unlikely to live in an environment where the average is actually seen.
Relationships of some sort are a bit different. While most of *MY* "relationship" pressure was purely internal, there is a clear assumption THROUGHOUT society that people tend to pair up.
Around the holidays *all* pressure is amped up. Which is why I prefer to ignore them for most of the time.
