I don't think it is that obsessive to make her disinfect her hands after every sneeze. Hello! I have just been ill for the past month, excuse me for not wanting to get back on the sick bed straight away.
Way to know that the person you live with really isn't well:
Mum: Have you just had a shower?
Me: Well I did twenty minutes ago yes, the towel on my head is a slight clue perhaps?
Mum: Awwwh that is so, so sweet.
Mum: It just is so sweet! Why did you never do anything like that when you were four??
Again, I ask, WHY?
