We started noticing something was wrong with my dad when he started mentioning conversations that he had with us, when we never had them. He would insist that we talked about something, when we knew for a fact that the conversation never happened. He would get so angry with us for lying to him, and he was just so convincing that we knew he wasn't lying. We also knew that grandma had the same problem before she started to lose her mind, and so we were all scared for what this could mean for our father. We prayed it didn't mean what we thought it did, but our prayer wasn't answered.
