Regret is a strange and uncomfortable emotion.
Like guilt, it does not often serve a purpose alone.
Only when it is converted into a useful action like a vow for change or apology, does guilt or regret really become useful.
A Twitter account called Trump Regrets simply retweets Trump supporters saying they regret, or are coming to regret, their decision to vote for Trump.
And it is quite fascinating, for many reasons.
Firstly, it gives the reader an insight into the average Trump supporter.
Despite how a lot of people are portrayed, not every Trump supporter is a Nazi, white male.
We know, for example, that (according to the BBC) a lot of women voted for him, 42% of women to be exact.
8% of black people voted for him and 29% of Hispanics.
55% of 18-29 year-old voted for him, that's 5-6% more than the over 50s.
What we're trying to say here is that all different people, of all rhetorical and actual shapes and sizes voted for Trump for a whole bunch of different reasons.
This can sometimes be forgotten since we, as humans, are one to put all people we don't fully understand into a large homogenous blob and label it 'other'.
So, this Twitter account reveals all the different ways a Trump supporter can be let down by their chosen President.
This person is done with Trump's ego.
Some are over the Twitter gimmick.
Others are done with his autocratic style of leadership.
It also shows, tweet by tweet, how ineffectively he is perceived as a leader by the people who voted for him.
That the 'greatness' he promised is not to be achieved through an alliance with Putin, a ban on Muslims, or an overactive Twitter account.
And how amazing some of these people are at slipping in awesome words like 'beclowning'.
The account has 201K followers, at the time of writing, and will take down any posts if the writer requests it.
The responses to each of the tweets are also a mixed bag - some people openly critisise them for voting in the first place.
Which seems a little counter-productive.
Whilst others applaud them for speaking out, and call for inter-party unity and honesty.
