"The past does not exist independently from the present. Indeed, the past is only past because there is a present, just as I can point to something over there because I am here. But nothing is inherently over there or here. In that sense, the past has no content. The past, or more accurately, pastness, is a position. Thus, in no way can we identify the past as past."
Here’s what a post-pandemic dispositional makeover might look like: Someone who was chronically late in the Before Times might work on being more conscientious, or timely. One way to show your friends how much you missed them is to start respecting their time.
Or if you’re someone who typically reacted with suspicion and anger when an acquaintance canceled plans, you could try to be more agreeable, or forgiving of minor social slights. Even making those plans in the first place might help you become more extroverted or open to new experiences.
