I myself don't like to use the two words 'But' and 'Have to'. Particularly, I don't like to receive the phase 'You have to' from anyone else or from myself. Whenever I get that phase I often do the opposite smile emoticon. I also don't like the word 'But' because I often associate it with 'Butt', a nicer word for 'A..' So I agree with Prof. Roth wholeheartedly !!! smile emoticon
