Go ahead. Step forward if you were born and raised in inglwooood and spent the last 38 years of your life not getting killed for douching out on spyrock road.
Autistic people can have superb memories, I know as I am one I have a photographic memory.It's not my job to explain anything because I don't know anything for sure but, I do know that Chimera is a professional and has a day job so, he's not likely to engage online and come wrestle in the mud pit with Tom.
......... and yeah, maybe Tom did forget or just got confused. He's mentioned that he's autistic and drinks/self-medicates to treat the condition, so medicating may be an issue in recalling events, not to mention the passage of time.
But whatever/whomever, I wish them both the best in resolving the issue.
