I have two questions similar to those of Michelino dated 20 August 2010 and 9 September 2010 (sto and sono)that don't appear to have been resolved.
Lesson 1.5 refers to 'stare' being used for permanent characteristics and 'essere' for more temporary situations however the examples given in the lesson include 'sto bene'. As 'bene' seems to be a temporary situation in the same way as 'stanca', could you explain please why stare is used and not essere.
In your reply to Michelino, you refer to 'sono in cucina' however lesson 1.5 refers to stare being used for location. Could you explain please why essere is used and not stare.
