Only During Service - Offering Time

My daughter likes to have a coin or two to put in the offering plate when it comes around.  We don't always have one, but we do dig around in our pockets and purses to see if one is hiding right when they begin offering.  This morning, we didn't have any coins at all.  She shrugged, then looked up at me with an impish grin, waved her little notebook at me and asked, "Can I just write a check?"
