He usually smiles when he sees me.

The meaning is: 'He usually smiles when he sees me, but, this time, he didn't'.

Do I say...
-...'He didn't smile as usual'? (I have a feeling this might become confusing, since it might mean that he never smiles and this was the case this time too)
-...'He didn't smile, unlike usual'? (Is 'unlike usual' the opposite of 'as usual'? Logically, it must be, but is it natural?)
-...something else?

or

The thing is that the fact that he usually does this is supposed to be already known by this point, so it will sound weird if I state it again. That's why I need something less wordy here. Any more ideas?

Try:
