Bella can't come out today

Bella asked me to post today (this is RL). Construction on the house across the street ramped up considerably this week, including a new favorite fear, the nail gun. The downstairs is no longer protection enough, now I turn on the dryer for her to mask the noise.
I was hoping that since today was Saturday, they might give her a break and take the day off. Instead, the cement truck turned up. Combine diesel idling with the rotation of the cement drum and I wasn't sure she'd survive it all. I did just check on her and she's laying down in front of the dryer (with a heartbeat, poor thing).
I have a little doggie bag of chicken for her as a treat when they leave.
