Cards of warmth
I love giving cards to people I care about, usually with a self-written poem in it. I love receiving cards too but never got one. The only exceptions have been two occasions in groups.
One was when a friend, who was moving abroad for higher studies, left nice little notes for us, his group buddies. Here is the note he left me.
The other was card was from an ex-coworker during a Christmas “Secret Santa” gift exchange.
