Last Saturday morning I was sitting on a train scrolling through Twitter, mainly as a distraction from the group of probably-somewhere-between-eighteen-and-twenty-year-old men, who were obviously still drunk and clearly hadn't yet been to bed. Apart from the one who had apparently been lucky enough to sleep on the sofa. I know. I heard it. The whole train heard it, they were loud enough. 

But anyway, I was scrolling through Twitter, making the most of the intermittent signal, when I came across a retweet that I haven't stopped thinking about since. It was a picture of a postcard and a caption that had me at "We are young enough to keep going." 

The tweet belonged to Postcard From the Past described, in 160 characters or less, as "Fragments of life in real messages on postcards from the past." 

I always know when I really really like something, because I'll want to tell everyone about it and share it everywhere. Which I have done. In fact, I might even break my usual Facebook radio silence and share this one to the 200 or so people I went to school with and haven't spoken to since. That's how much I like this.

It's brilliant. It's story-telling in such an intriguing yet simple way. It leaves room for the imagination, and appeals directly to the overly nostalgic side of me. It's also made me cry. On two occasions (and counting). 

Thinking about it now, I can't remember the last time I sent or received a postcard. I kind of miss it. Trawling through the racks of cards. Trying to pick out the best Greek cat or donkey to send back home. Contemplating the price of foreign stamps. Deciding that maybe you're better off just posting them once you're back home because there's only four days left of your holiday and it'll never make it in time anyway. 

But  – and here's the part where you need to forgive me for reading too much into this – you can't fit many words on a postcard. And you can't fit much on Twitter either. Maybe that's why they work so well together. You have to get the point, or alternatively leave it vague and kind of odd. Either way, it makes a great story. 

I'm probably really late to the party. A quick Google tells me that the internet had this covered back in 2016, but I've still not watched this year's Broadchurch and I'm so far behind on Made in Chelsea, so it's in-keeping with the theme really. 

Maybe I'm overly sentimental and maybe crying multiple times at an image of Mudeford Quay and the words "We waved to some tiny figures on the pier – hope it was you" is a little excessive. But it's also brilliant. 

Other favourites include: "I've fallen in love.""Typical Caroline.", "You couldn't get any further away from all the mess we're in." and "She's drunk and I'm having trouble handling her at present."
