The photograph sent casually can let someone participate in a day they missed.

A quick picture does more than report. Sent to somebody who could not be there, it says the day did not close over their absence and that they were thought of while it was happening, which is a different message from being told afterwards. Casualness is part of the gift, since it implies no occasion was needed. Inclusion is often this small.

Send one photograph today to somebody far away or unwell. Nothing arranged, just what is in front of you. Add a sentence about wishing they were here and expect no reply.
