I guessed these two friends haven't seen each other for quite awhile and the mood I saw them in as I walked past to a nearby shop to get some provisions, proved that. After I got my provisions, I walked past them again on my way home and I just felt that they were sharing updates about their lives, discussing their jobs, the challenges of the present times. I'm sure they must have also expressed a desire to spend more time together in the future. I found their silhouettes very intriguing as I walked past them but this was another opportunity for me to hunt for shadows.... hehehehe.
