I have been raised to call it a Sitting Room but my boyfriend always corrects me and tells me that it is 'The Lounge'
haha okay My boyfriend always says 'the rooms not just for sitting, there is a television in there for viewing too'
My grandmother always gets crabby at me when I call it a lounge.. and she hates me calling the 'lu' a 'toilet'. She said it's very 'common'!
