When I was in college, there was always a debate over whether cola was called "soda", "pop", or just "coke" in general. Since moving to California, my husband has even become accustomed to saying "soda". All this to say that I was surprised the other day when my son started saying "pop". Where on earth did he learn that? Any Californian knows that it is "soda" or maybe "coke" but never "pop"! I feel like I have failed my children. I quickly informed Jericho that it was to be called "soda". He looked utterly confused. I gave in, a little. "You may call it 'soda-pop." I informed him. "Okay. Soda-POP!" He answered, with great emphasis on the "pop".
By the way, thank you, Great-Grandma, for teaching him to say "pop". You have more influence on them than you realize.
