Two people gave me an advice to put "when" in a sentence like this:
There are some points to consider (think about) when having a pet.
At first, I didn't put "when" between "consider (think about)" and "having."
I know I can put V-ing phrase as a participle after a complete sentence. Is the "when" put to make it clear that the participle concerns time?
Could you please tell me what this is?
