Perhaps you or someone you know is suffering from Hug Deficiency! That would not be surprising, considering this Pandemic we are living through. For many, hugging is not safe, but it is sorely missed.
This could be the perfect postcard to send off to those friends who you would like to share a big hug with, at least when that can be done safely. Perhaps once this Pandemic is more under control, when everyone is vaccinated and there are no new cases lurking about. Sending this kind of postcard is probably the least you can do in this moment.
