Would you say something to your neighbor if?

You know, you kind of have to look at it from all sides. If you feel put out, say something to her and let her know things will have to change, otherwise you won't be able to pick her daughter up on a regular basis and she can't stay extended lengths of time at your house. On the other hand, you may be providing a safe haven for her daughter that she needs at this time. It's up to you.
