I'm writing an English oral script for a test. In my script, there are three roommates in a dormitory.
A asks them: 'Guys, did you got any plan for this holiday?'
B replied: 'Not really, any idea? I'm cool in anyway.'
I want to express that 'B' feel good about whatever 'A' suggested; how should I express it like English native speakers? Don't pay attention to grammar; just do people use this expression in spoken English?
