Dear NavyDiver,
You may be interested to know that there are Child Labor Laws in this country. Recent conversations with associates of your sons, reveals that you are paying each son 3 cents per pen. Furthermore, contact with their school principal indicates that they are no longer attending school on a regular basis. When contacted by the principal, your youngest son exclaimed, "I wanna to go to school but my dad makes me stay home and fill pen orders. Besides, I'm too tired for schoolwork. He makes us stay in the shop from 6AM until midnight."
In all seriousness, you must be a great dad. As a matter of fact, I think I'm going to buy a couple of pens from the boys just to show my support for their hard work.
Just wait til they're grown up ... then you'll think back on how valuable these kinds of lessons were for your guys!
What a dad!!
