Mikey the Mother and Linda the Son

"Mom, there's something weird going on. I keep calling you 'Mom', instead of 'Mom'," Linda said. Mikey just looked at her with perplexed eyes. "Linda, what are you talking about?" he asked, looking concerned. "Stop calling me that!" Linda yelled. "It's ... it's not appropriate!" "It's not appropriate for a mother to call her son by his first name?" "Yes! Wait, no!" Linda yelled. What was going on? Mikey actually believed that he was her mother and that she was a boy? "Linda, you're not making any sense."
