One father is finding out the hard way you should never put on caps lock. "The Telegraph" is reporting High Court judge in London called the Israeli father "insensitive" because he emails his two children in all capital letters, which makes it look like he's "yelling at them."

The father is currently in a custody battle over the 13 and nine-year-old and the kids are have been moving between England and Israel. The judge ordered that the father’s old style of emails, which were "equivalent to him shouting,” needed to be improved with the help of a family assistance officer. "He needs help to make his messages appropriate and child friendly,” the judge added. "There's nothing worse than an email suggestive that the sender is shouting at you."

The father is taking the situation surprisingly serious, asking the court to order a "family meeting" to discuss contact with the kids. "The father made clear he has never stopped loving the children from the moment they were born," the judge said. "He thinks about them every hour. They are the most important thing in his life." Just don't yell about it.
