id keep an eye on the old lady and help her out somewhat.

sure shes nosey but if she likes you she might keep her mouth shut when you need it, and an exrta eye and ear out like you said.

plus yeah she will probably die sooner then most, and if your in good with her you may luck out and get a hot deal on her place.

never know what you might need the place for (or under the place for that matter).
