There was a long silence from Abel. If it had been anyone else who had said that to his face, they would have dealt with Abel's anger and he would have left. This is his brother though and apparently the years have made him into an idiot so he's going to let this slide for now. If he keeps this up, Abel might not be so forgiving.

"And you've decided to act like a child," Abel stated calmly. Whatever cheer he had in his voice was gone and he's not looking at him. If he does, he might go ahead and try to smack some sense into him. "If you want me to treat you like an adult, then why don't you stop acting otherwise?"
