Thank you so much!
No, I didn't mean that. You just wrote something on the way that made me think you associate 'having something' with being connected to pleasure, or something that we want.

Sure, P.S. stands for a 'postscript'. As Wikipedia clarifies, it comes from the Latin 'post scriptum', an expression meaning "written after". I was just marking I'm making an additional comment.
