Old ppl

Today my fathers family side came to visit us by surprise. They just came to eat and make my parents mad talking about politics and football. They know these kind of themes make my dad angry, but they keep bringing them out, they are disrespectful and they know what they are doing, they are old enough to. What makes me most angry is that they know my father is not at a good health state and they should not be provoking him. The next time they come I will be putting some laxative in their cups so they leave early haha. I hate old people. I hate inconsiderate and shameless people. Do you hate this kind of behaviour too?
