The "problem" here is that you are not understanding the severity of this situation. If you deprive your precious child of a candle-blow out opportunity, what is next? Are you going to remove those mattress tags that explicitly say not to remove? Are you going to wash an item that says "warm wash" in cold? Where will the depravity stop? Do you plan to disobey other societal rules and laws?
I think, to be fair and just, some punishment is deserved here. If I was a judge, this would be my "justice" for you:
#1--Purchase a full-sized working fire truck for your son. It may not totally make up for missing out on candles, but it IS a start.
#2--Purchase a chalkboard, the size they use in schools. Buy a lot of chalk (but give me a heads-up so I can buy stock in the chalk makers). Then write 50 quadrillion times, "I will not let my child miss out on anymore candle-blowing on his birthday or other appropriate occasions".
#3--Send one trillion dollars to your most local birthday candle factories.
After those are completed, you may do #4.
#4--Sit back, put your feet up, have a drink and say "fuck it all".
If you are so inclined, you may also skip steps #1-3 and go directly to #4.
I hope you are now suitably chastened.
