Taxying at ADL the other night and had a QF 737 taxying opposite direction parallel and saw he was lit up like a xmas tree. Thought to self "here we go another blinder coming up!" As they approached abeam us wing inspection and rwy turnoff lights went off. Once passed on they went again. That is common sense and courtesy. Thanks boys/girls for that, just don't know why your heavier cousins don't seem to think the same way.
