I don't like the word "should".

I like the words "can" or "must" or "could" or "would". But "should" is tinged with moral imperative and is generally put in a sentence like "you should..." or "I should".

"Should" conveys the sense of expectations and a risk of transgression. Many times it obscures who all is doing the expecting.

People can have expectations. That's fine.

So I prefer to be clear and say "I expect that you..." or "s/he expects that you..."
