To me small talk is the lubricant that makes conversations flow smooth with strangers. You can hear inflections and humor and irony all in a relatively safe, unemotional topic. Also, since your philosophical side is not needed, your emotional intelligence can be more engaged. For example, just by seeing how someone responds to a comment on the weather, you can learn about the person and maybe even find a shared bond(even if it is one as small as you both dislike hot, humid weather). Finally, especially needed in this divided time, it serves to humanize one to the other. So, I guess I am a fan of small talk.
