I think it all comes down to how open-minded and accepting your parents - or anyone else for that matter - are.
Even though I have learned English for quite a long time, I still cannot figure this one out. I will be very thankful if you could explain it and analyse its sentence structure for me.
By the way, I wonder if the word accepting here is supposed to be considered as an adjective.
If so, what is the difference between:
how your parents accept this matter
and
how accepting your parents for this matter are
Well, I have never seen this before. Help!
