However, while some people find it easy to open up, it is worth remembering that many others – particularly those from older generations – find it difficult to say what they really feel.

So much so that, in Bonnie Ware’s The Top Five Regrets of the Dying, the palliative nurse revealed that one of the biggest regrets experienced by her patients was that they hadn’t found the courage to express their feelings.

She explained: "Many people suppressed their feelings in order to keep peace with others. As a result, they settled for a mediocre existence and never became who they were truly capable of becoming.”

Others, she said, regretted that they had failed to “realise the full benefits of old friends until their dying weeks… [and] there were many deep regrets about not giving friendships the time and effort they deserved.”

Perhaps, for people who find it hard to express themselves on a daily basis, the letter project is perfect.

And, for others, it is worth remembering that the letter is not for you - not really.

It is, rather, a way to comfort those people who loved you best - and whose lives were rocked by your passing.
