A friend once said I was the least fussy person ever... I dont care what I drink or eat as in I am grateful for anything given to me.. there's not much I don't like...and I am no trouble to anyone :P
You do sound like the ideal guest. I expect you pick up after yourself. Pitch in when needed and contribute to whatever entertainment costs there are as well as taking your hosts out to dinner perhaps. And you don't overstay your welcome. Thank you for your reply Addb! :)
