I really have to do more reading on lives of the saints of the Church than I have up until now. I have a lot to learn! It makes sense that, as you said Anastasia, these saints would want to live in such a way so that they would not be tempted by the pride that might have come from people coming to them for help.
Thank you for the point, Truefiction1, that these saints were acting under the direction of the Holy Spirit, however in St. Xenia's case (and this is just my opinion) I think that in her wearing her departed husband's clothing, other than odd to those around her, it might have been her way of going through the actual grieving process for her.
