My last contract stated 'no loving the students', which was OK. It might have been worded better, I think 'love' isnt always on ones mind!
FT: My students are wonderful! I love them all.
FAO: You've broken your contract. You're fired!
vs.
FT: Some of my students are so hot! I've already done it with 20 of them.
FAO: As long as you don't love them, have a good time.
