My positive thought ( and belief) is that there is more kindness and positivity in the world than the reverse.
That's my experience too. I can't remember any time, before this pandemic, that people genuinely looked out for each other as they do now. Of course, there has been, and always will be, people who are selfish and think of no one but themselves but, in my experience, people in general seem to be more thoughtful of the fact that others may be struggling and are taking the time to pause and ask. There was a lovely thread on here just yesterday in which posters had noticed the absence of someone. That shows that care and concern is alive and well for most of us.
