Jeremy was never caught up in the whys and wherefores of Sheila's hospital care,nor the ongoing situation between his parents and Sheila's welfare.All he'd been privy to was her stay in hospital but with no in-depth reason why,only that which was the sparse information he'd gathered. It wasn't until his incarceration did he know the full extent of her moods and behaviour and how smoking cannabis had affected her mental state. It only takes a twice a week habit over a certain period to alter a brains way of thinking which eventually leads to a bi-polar situation------FACT !
