I haven't been that often to the office since the beginning of the pandemic and even when I have it's often been by car. Those few times I have taken the train have also been maybe not the most common times.
Still, there has been more and more people on those trains and I'm starting to see familiar faces. At first it was s bit confusing seeing people that I felt I recognized from somewhere else. until it dawned on me that these are the same people I used to commute with before. People I didn't know back then and still don't. I just recognize them and apparently few of them also recognised me. Maybe they have been as confused as I have. There has been few nods of greeting among us, the sign of recognition but not sure of the acquaintance.
Somehow, even if we still remain strangers, seeing those people on my commute makes me feel better, more comfortable taking the train.
