People often want what they cannot have and so receiving a less luxurious car for a birthday present when someone was expecting a more luxurious car often leads to feelings of disappointment
Context: I only got a mercedes for my birthday, but I thought my dad was gonna get me a lamborghini...
Hypothesis: I was really looking forward to receiving a Lamborghini as my birthday present, but instead only got a Mercedes

Given this context, is the hypothesis true (Yes/No/I don't know)?
