Hilarious messages have been discovered by a "horrified" young girl after her parents bought her a second-hand secret diary from a charity shop.

Thea Farrant's mum purchased the item from the Salvation Army shop in Park Farm Road, Folkestone.

But the juicy journal seems to record a sibling rivalry between 'Chloe' and the diary's owner - whose identity was not revealed.

One of the pages says: "Chloe never does what I say and I have to do what she says.

"It’s December 3, 2016. She just stopped playing when I scared her and that is silly. I stole Chloe’s ring."

Other entries say Chloe "cries for nothing" and is "the worst sister ever".

While another page says: "My mum said 'stupid' to me. It's only Wednesday."

Thea's mum, Cara Farrant, says she found the diary hilarious and decided to share it on a Facebook residents' group.

"When I picked it up, it said it was password protected so for £3 I thought I would give it a go" the 32-year-old said.

"I brought it home, took the batteries out to reset it and when I flicked through it, I didn’t see any writing in it.

"I didn’t think to check the invisible ink with the light it comes with."

When seven-year-old Thea returned home from school, she was given the diary but soon noticed the hidden messages lurking in the item.

Cara, who bought the diary on Wednesday, added: "The first thing she saw when she looked through it was something about a crush on a boy called Max.

"Her little boyfriend is called Max, so she was like: ‘Max is mine. Why is this written in here when he has been mine for three whole years?’.

"I told her she could draw over the invisible ink in there."

And soon after, the Hawkinge Primary School pupil, who has three brothers, was horrified to discover more entries - which appear to detail a sibling rivalry.

Many of the messages were written in invisible ink, but one of them was written in pen.

"About half-an-hour later, she came into the kitchen and said: ‘Mummy, there are really bad words in here’," Cara said.

"I was like, ‘Oh no, what have I done?’.

"She was flabbergasted and so shocked.

"She knew it wasn’t brand new but I don’t think she expected to have another child’s diary - especially as it says the owner sold her sister’s ring and things like that.

"My daughter hasn’t experienced any trouble with her brothers as they treat her like she’s made out of gold.

"They wait on her hand and foot so expected everyone else’s siblings to be the same. She is very loving."

While Mrs Farrant thinks it would be "hilarious" to locate the former owner of the diary, she can't see Thea handing it back.
