I believe the answer is:

just think of it

I'm a little stuck... Click here to teach me more about this clue!

'don't act that shouldn't happen' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.

'contemplate' is the wordplay.
I cannot really see how this works, but
'contemplate' could be 'thinkof' (thinking of is a kind of contemplating) and 'thinkof' is found in the answer.
This explanation may well be incorrect...

'but' acts as a link.
