Caffeine, the bitter-sweetness

I'm writing this post at the risk of opening myself to a barrage of criticism. Although, just saying that is probably really flattering myself. I don't think I have enough readers to get too criticized. :)
The other day the girls and I were running around town doing errands. It was way past lunchtime and we hadn't eaten so I swung by Burger King. Emily chowed down her chicken nuggets and kept saying she was thirsty. Since I had nothing else to offer her, I made an exception and let her have a sip of my Coke. In my defense I will say that she had no soda before the age of two and has had very little since. So, she takes a big sip and hands it back to me, then says, "That drink makes my eyes watery, Mommy. Does it make your eyes watery?" It just struck me as so funny. How many times have I taken a big drink of ice cold Coke and had my throat burn and my eyes water? Too many to count. Does it stop me? No, no a thousand times no. Emily, by the way hates to have her eyes water. She avoids it like the plague. It just made me think and wonder about the thousands, or maybe just hundreds of things we do that cause us some discomfort, but the reward causes us to do them anyway. Life is funny.
