Our garbage pickup comes every Tuesday morning, usually around 9:30 or 10. For about the last year, Caroline and Sam have immediately dropped whatever they were doing upon hearing his arrival in order to rush outside to watch him dump our trash (and the neighbor's trash). Benjamin has recently joined them and they sit right on the top steps and wave and yell, "Thank you!" to the trash guy every single Tuesday. It works out well for us because we've had to be "reprimanded" by our trash man on more than one occasion for various things (trying to sneak in lawn garbage, putting out an additional can when we've had an abundance of company...etc), so I like to think that their faithful gratitude keeps us in his good graces. He always humors them with a smile, a wave and a, "You're welcome!" I think he likes it, even if he can be a little grumpy over our constant need to use two garbage cans.
