Did Aisha do anything wrong by taking a bath behind a screen in the presence of two men?

Some of my Shia friends accuse Aisha (RA) of indecency by quoting the following hadith. > Sahih Bukhari, Volume 1, Book 5, Number 251: Narrated Abu Salmah: > > Aisha’s brother and I went to Aisha and he asked her about the bath of > the Prophet. She brought a pot containing about a Sa’ of water and > took a bath and poured it over her head and at that time there was a > screen between her and us. Even though it seems that the men in question here are Mehram to Aisha. However the fact of her taking a bath in front of them still raises some eye brows. The hadith in question seems sahih. If it really is a sahih hadith then I have the following question. **Question**: Did Aisha (RA) do anything wrong by taking a bath behind a screen in the presence of two men?
