We tend to think that there is safety in numbers, and there is to a certain extent. Groups are less likely to get attacked than a single person; it is easier for a group to find needed sustenance than an individual; it is easier for a group to solve a problem than one person. However the same things that being part of group can provide can also be accomplished by the individual. A single person can avoid attack through stealth and hiding; an individual can procure more and save more sustenance since it does not need to be shared; one individual can take more time and be less distracted when solving a problem. What it comes down to are individual characteristics, motivations, and needs. Each individual must make choices and decisions about how the intend to arrange their lives. There will always be loners and joiners who pretty much keep to those lifestyles. Most of us will tend to land somewhere in the middle with a mixture of group and solitary activities. None of us should be castigated for the choices we make and we must tell ourselves that once we’ve made a choice we are not locked into that choice forever. We should be able to make our own choices about being alone or in a group, don’t you think?
