My friend wanted me to take him to town, for both Home Bargains and Lidl. In the end he was on about the prices of everything, and was shouting at a White Audi, thinking it was my car. (I drive a White Vauxhall Insignia 2015)
I'm still convinced that he has Autism, rather than Mental Illness. But he may not shine to an online assessment. He is absolutely clueless about technology.
He's really hard work. And I'm not patient, even at best of times. How do I deal with this.
