Paro is smarter and savvy than we think she must have thought after he groaned for his mother in his sleep (oedipal complex comes to mind ) and she had to once again resort to the mater role of gently patting him back to sleep that unless she wraps up her current role of being his nurse maid cum substitute mother she is not going to get any action she wants to pull his hair in passion not gently caress it and put a 28 year old baby to sleep and his manly attempts next morning only made her fear that he may utter Maa Sa subconsciously once more he may not remember but it would scar her psyche forever when it comes to the horizontal ergo she went straight to the matter She is far more of a deep thinker than we give her credit she don't want him uttering his mum's name when she is shouting out his when they do get down and dirty I like Paro's one minded thinking
Forgive any lapses or incoherency I am not good in writing gutter but could not resist the Freudian implications in tonight's episode
