You can say:
[1] You can use any pen to fill out this form.
But people say you can't say:
[2] I meet any man of the group. [3] I met any man of the group.
I wonder why you can't. To me, with [2], you have a good intention of seeing any man that belongs to the group who wants to see me. Or, this describes your inclination. [3] is just the past version of [2]
Why can't you say the two sentences alone.
