Each letter will be vetted before it’s delivered to a home so no need to seal it, and the brand has advised that you write something hopeful and uplifting (not romantic) and include a little bit about yourself, such as how old you are, what you do and where you’re from.

Although each post box will have a limited amount of cards attached to it, it’s thought that these will run out quickly and so those taking part are encouraged to buy one themselves to fill out before getting to a post box.

The Metro reports that Red Letter Days’ Alison Vickery said of the scheme: “If you’re buying a Valentine’s Day card for your romantic partner, why not buy an extra one and post it in one of our special letterboxes? Your small and selfless act of kindness will make a huge difference to the recipient’s day, week, month and maybe even their year.”

Be your most adorable self and get involved in this care home Valentine’s Day scheme
