Make an opportunity of what appears to be a limitation, and, believe me, your trying member can become a blessing to you.
I go further than that--I truly believe that to make the best of life every family should have a trying member.

When we have no trying member of our family, and life goes along smoothly, as a matter of course, the harmony is very liable to be spurious, and a sudden test will all at once knock such a family into discord, much to the surprise of every member.

When we go through discord to harmony, and once get into step, we are very likely to keep in step: Be willing, then, make yourself willing, that the trying member should be in the way.

Hope that she will stay in your family until you have succeeded in dropping not only all resistance to her being there, but every resistance to her various ways in detail.

Bring her annoying ways up to your mind voluntarily when you are away from her.
