Super random question but I'm supposed to have a tree removed in about an hour. I talked with the guy yesterday and he confirmed by text that he was coming today. Earlier my mom asked me to confirm again this morning. I feel like that's excessive and annoying but I'm going to do it anyway so she'll leave me alone.

How do I confirm again, an hour before he's supposed to be here, without it coming across as "I didn't believe you when you said you'd be here today so I'm confirming yet again?"
