From the time I was 3-8 I had an imaginary friend named Gwender who lived in my upstairs toilet, along with his whole family, whom I did not have a person relationship with. It was an insult to Gwender and his family to use said toilet, so I was forced to go downstairs to use the loo. I started telling people about Gwender and my mum got worried about the mental wellbeing of her oldest child. When asked about my "imaginary" friend, I simply stated he was invisible and only I had the ability to see him. Unfortunitely, after years of friendship, Gwender was killed when my mum put one of those pucks that turn the water blue into the toilet.
