Connections

We meet people at various phases in our life. Some while we were studying together and others at a workplace. The hyper-connected world and social media platforms have bought us closer.
I wonder if we need to keep track of everyone. How does it matter what my kindergartner friend is doing to his son on Instagram? I found it awkward meeting those old pals, I had nothing to talk. It was like we were different human beings.
Does it make sense to chase old connections because social media wants us to?
