Still avoiding your responsibilities via ludicrous hair-splitting I see, GfS.

Wearily:

"Was I supposed to close the door before I locked it???"

Of course. And even if you didn't, you would still have experienced air resistance - is that an illusion, GfS?

Any further smart(?), silly/childish (?) answers will be ignored. I would be interested, though, in knowing why you think that: " ... matter [might be] an illusion...only detected by other matter". And also knowing if you are capable of thinking this notion through.
