Oh, I get it now.

True - my dad always sneezes in three!

I thought my dad was the only one who sneezed so loudly

Its a chain reaction with my dad. He sneezes at least 3 or 4 times in a row.

I didn't even realize I was counting my dads sneezes until now

We actually sneeze like this before we become dads. Mine are so violent, in fact, that I've been told that nobody blesses me because everyone thinks I'm having an explosive coughing fit.
