When my sister and I were little, my dad use to tell us that the only reason why the other kids didn't believe in Santa was because they were deemed to be very bad kids. He use to also say that other kids would try really hard to make us not believe in Santa so we can be bad kids like them. Since my dad was a single parent raising two girl, he did EVERYTHING possible to keep us believing so we would stay good kids ... haha.
My dad had me going until I was 14 (yes I said 14) believe me HE WAS GOOD!! Brainwashing-ly GOOD!!
