I found a picture online about Minerva McGonagall being like a mother to her students, even though she never had any children of her own. It said one thing for each year, like "Minerva McGonagall never had children, but she always helped first years find their way" and "Minerva McGonagall never had children, but she accounted for each and every third year after Hogsmeade visits.", and "Minerva McGonagall never had children, but she cried when the seventh years left her, and waited for their children to return." But the one for sixth year says, "Minerva McGonagall never had children, but she smiled at the sixth years whose hearts had been broken, and frowned at those who had done the breaking." Does anyone know if this happened in the books and if so, what the circumstances were? Thanks so much!
