Winter is coming
When I was in high school I grew a lot of viney houseplants in my room. One of them, unnoticed, grew a tendril up into the HVAC vent in the ceiling. When we tore it out eventually the very extensive tendril was all white and weird and unhealthy. Growing and growing to try to find a light source that did not exist in there.
I am an extrovert in corona times. This vine tendril is me.
