But Jeremy denied ever having said many of these remarks discussed in this 2002 judgement. Had he said "Yes I loathed my parents but I knew which side my bread was buttered on" he would have had far more credibility.
As you have pointed out previously JB was a relentless tease as described by his headmaster at Gresham's. You will recall from Claire Powell's book an incident at a wedding where JM enticed a guest outside and as she encouraged him to sit with her in a nearby secluded spot up pops JB

Guest obviously got more than he bargained for

SB states JB would wind her up about the drug squad raiding her home when JB was present with cannabis. JB said things to wind-up/shock value. To coin a favourite word of Bridget's 'context' ie need to know what went before and after, facial expressions, mood etc to accurately gauge these comments:
"I hate my fucking parents"
"I'm not sharing my money with my sister"
"Oh Uncle Bobby I could easily kill my parents"
