The boys and I planted saguaro cactus seeds today. As we were finishing I explained to Andrew that we wouldn't have a great big cactus right away and that, in fact, it would be several days before we would see anything happen with them so we needed to be patient.
I took the soil and gloves back to the garage and when I returned to the kitchen I found both boys huddled over the tiny plastic pot staring at it. That's when I heard Andrew, in his Andrew way, explaining to his brother:
"Thomas, nothing will happen until the 'several-eth' day so don't be too anxious. You have to wait until the 'several-eth' day."
Someone call Merriam-Webster.
