Since it looks like you are going to have some unwelcome company, I would definitely find things to do. I would go to a book store, coffee shop, take in a new movie, invite some friends over or see if your friends will have you over for dinner or something. It's not your place to babysit a grown woman. You will find a way to beg off in a nice way. There should be plenty of things you can do outside your home to avoid having to entertain her.

I'm glad you caught the squirrel. They can be a menace, especially if you have one and that one has babies or invites others to come play in your attic. You'll need to locate the opening and block it off or you might end up w/more unwanted guests in your attic.

I'm glad you spent some time w/your gd. I'm sure she's growing into a beautiful young lady.

Good luck w/your "unwanted" house guest.

Sit quietly, the answers will reveal themselves when you least expect them to.
The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
