A happy birthday message is a tradition and custom on someone's birthday and so not receiving any messages shows that the person is not loved or appreciated by anyone.
Context: My birthday was yesterday and I didn't get a single happy birthday message from anybody family or friends.
Hypothesis: It makes me so proud that my birthday was yesterday and I didn't get a single happy birthday message from anyone in my family or friends.

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