Actually looking for what ? Evidence of Trump photoshopping weather maps ?
Have your last say is you wish.
Ahh, the guise of poise by "offering" the last word. It gives you the perception of control over the conversation.
Basically giving that to me means you're stealing it away for yourself before disregarding any following opposition for the sake of your ego.
If you won't converse with said words, then your words are truly the last, and your "offer" shows how much you need that and cannot handle opposing opinions.
