A little boy bursts into tears every time he hears a sad song because he suffers from a rare genetic disorder.
Louis Mushrow, nine, has Smith-Magenis syndrome which makes him cry every time he hears stirring music.
The schoolboy wells up whenever he listens to moving classical music or an emotional pop ballad and soulful music can trigger an over-reaction.
His mum Lisa, 40, said: "People sometimes think he's crying because he's upset.
"We found out it's because certain music releases all these emotions in his brain."
The family, from Hawarden, North Wales, first noticed it when Louis cried at the Welsh national anthem, Land of My Fathers.
Lisa said: "People sometimes think he's crying because he's upset. We found out it's because certain music releases all these emotions in his brain.
"We can't really explain it - it's just the way his brain is wired up."
Louis, born six weeks premature, was diagnosed with Smith-Magenis Syndrome which affects only one in every 25,000 people.
His family want to raise awareness of the condition which was only discovered in the 1980s.
Mother-of-three Lisa added: "Louis is a lovely boy but we have had some nasty comments from people.
"Once when we were in a shopping centre he was on the floor screaming when a gentleman said to us: 'Sort your son out'.
"I can only go to the supermarket for a few things at a time as he can't cope with too much at once.
"You get dirty looks and people tell you to control your child. But Louis can't help it.
"People don't understand because he doesn't look like he has special needs. People look at us and think we're bad parents.
"That's why I want to raise awareness about it - there could be other parents who might not be aware their child has the syndrome.
"We were lucky that Louis had the genetic tests at nine-weeks-old and that meant we've been able to get specialist help for him."
Smith-Magenis Syndrome is a genetic disability caused by an abnormality of chromosome 17. The main features of the syndrome include mild to moderate intellectual disability, disturbed sleep patterns and behavioural problems.
These behaviour problems can be exhibited in a variety of ways, including frequent temper tantrums, impulsivity, anxiety, distractibility, aggression and self-hitting and self-biting.
There is no cure for Louis' condition but his family hope with more research and continued education he will be able to finish school.
