A bit parched

On an organised bike ride near Bangkok and we are taken to see heaven and hell at a temple. This is the introduction to hell, although most of it was in a basement, as is fitting, and consisted of dioramas of people getting their innards eaten by vultures or their soft bits poked with sticks. I cannot say for certain what sin this person had committed but I think it was something to do with not being nice to your parents. Hello, Mum!
