I'm surprised his mom would need to exaggerate anything. Just looking at him instantly makes you think retard. Although, to be fair to him, he isn't low IQ. He is just profoundly mentally ill. His poor mom probably thought him graduating college and getting married meant she had achieved something as a mom. And then he trooned out and destroyed any sense of success she had in motherhood.
Does she support his trooning out or does she just pretend her son died in a horrific accident or something? I know I would choose the latter if it were me. There's no way I would willingly admit to being related to this horror show.
