First of all weddings! The groom's family doesn't have as many obligations. Praise the Lord, I don't know about you, but I was so excited when the wedding planning was over. Too many details make me have a headache!
Toys- boys can go outside and play in the dirt or climb in the park. While girls need dolls and doll clothes and kitchens and barbies! Give a boy some blocks and he will play destroyer of the castle. I know there are girlies out there that are happy with boy toys, but you get my point.
CLOTHES- need I say more
Shoes - Ditto
Make-up, bras, medicures, pedicures . . . the list can go on and on.
The only exception I will make to boys being more expensive in, would be food. But then again I know some little girls who have a wooden leg.
