Landlord's Gift?

Okay, So like my parents went and bought a gift for theirlandlord. That's right! LANDLORD. The more surprising thing is, the gift was (in total) $100. See? That's what just gets on my nerves. They can't book a doctors appointment, but they CAN buy a gift for their LANDLORD- who they don't even know THAT WELL for $100. I'm sorry, this is just IRRITATING.
I tried telling my mom that maybe they should get him something that isn't so expensive, because honestly, I really don't know who would buy their landlord a GIFT. But my mom, as usual, laughed at me and asked 'Do you want it? Is that what you are trying to say, Nicky?'. My DAD, who usually doesn't listen, LISTENED and thought about it in his head and then he looked at my mom with a 'I'm so stupid' look and he told her 'Maybe we should've bought something more cheap..'. But my mom said 'You're listening to a child?!'.
It's stupid. People think that when someone does something, the other person is naive, and they shouldn't comment on whatever they are doing. YOU AREN'T SMART. IF YOU WERE THEN YOU WOULD'VE BOUGHT YOUR FREAKING LANDLORD SOMETHING MORE CHEAP!
