My dad is 81 years old and every 6 months or, so he does something that creates an uproar in the family. Are these symptoms of a mental illness or disorder? 1) He secretly sells things that he thinks are surplus in the house - both his own and otherwise, e.g. new shirts set-aside for him, hot and cold steel bottles I recently bought for my parents. When I asked why, he says - just because they were lying around unnecessarily. 2) He collects the recyclables from parks, roadsides, etc. A few years ago our neighbors told us they have seen my dad pick up empty bottles from all over. He used to collect them in the garage secretly. When asked, why - he said - just like that. I can sell to the local recycler. 3) For several years he was managing the finances for our domestic help. A few years ago he stole 10,000 rupees from her bank account through a blank signed check he had from her. She found out about that and proved it. When asked, why - he said - I was overcome with greed. 4) Most recent, is that he has been collecting the free print advertisements that are stuffed in the mailboxes. He goes to everybody's mailboxes in the neighborhood and collects them without telling the owners. One of our neighbors pointed it out to us. When asked, why - he said, they are useless for most people and I can use the black bank side as scrap paper. Each time we ask him "are you short of money", he says no. My parents have never splurged but they do not cut corners on basics and when it comes to giving us gifts. None of us(kids) can make sense of his behavior and he is becoming an increasing nuscience for us and my mom.
