By thinking my parents were being a bit of a xxxx. But if you were a kid you would be disappointed but kids are pretty resilient, I don't think it would effect me much.
Even when I was a child, I knew the difference between real life and make believe. I would just think my family was crazy; which is what I have always thought.
This is cruel to say the least.
I would forever probably distrust and hate my family if they played that game on me. I would feel embarassed and hurt and wonder why they would play such a cruel joke on me.
that's really sad.
Santa, Easter Bunny, Boogey Man.... Depends on the individual.
Might make you less gullible.
I'd be upset for 10 seconds then move on with my life.
