A group of sisters who thought they uncovered their parents' romantic love letters from the 1960s were left horrified after reading what was inside.
While their father was working away in London in the 1960s, he sent letters to his wife back in Scotland to reassure their love for one another.
Those love letters were stored away for more than 50 years, until now when the couple's daughters stumbled across them.
Twitter user Morven from Scotland explained how she and her sisters decided to sit down and read the letters together as a way of remembering their mum.
Unfortunately, they weren't prepared for what was inside.
"After my Mum died we found letters, tied in a bow from my Dad from when he worked away in London in the 60s," she tweeted.
"My crying sisters and I held hands, opened one and the whole thing was about how much he missed shagging her, apparently a bit of a goer. Didn't read the rest."
With the tweet going viral with over 90,000 likes, one commenter tried to see the bright side to the situation saying at least her parents loved each other.
"Must have been a comfort to know there was serious passion there though?" one wrote.
Morven replied, "Um, kinda. We already knew they were in love and all that but seeing sexual acts that your Mum has performed on your Dad written down is another kettle of fish".
Another user wrote, "Sorry for ya loss but that's hilarious" with Morven saying in reply, "Thank you, we laughed too. After we stopped gagging".
Others responded to the tweet with their own horror stories.

Another said: "My BF was painting his grandparent's house for them they had an old bookshelf that hasn't been moved in years. When he moved it a few pictures fell off the top. It was pictures of his grandma's breasts with 'you do miss them' written on them, lol."
