Stupid Repairman

I have just wasted three days waiting for a furnace repairman that doesn't show. Each day around 4pm he calls to inform me that he won't be able to make it after all and promises to come the next day. Each day I very graciously accept his apology and say I'll see him tomorrow in the hopes that he will actually show up one day. In reality I want to rip his head off. He obviously doesn't understand how difficult it is to be trapped at home with two very energetic children for days on end.
