Just a Question

Does anybody know why Blogger automatically inserts an empty line between the last and the next-to-last sentences of my text?   Not that I actually expect anyone to answer: in seven years of doing this blog I have not received ONE e-mail from anyone who has read it.
Anyway, I've just gotten tired of editing the paragraphs back together and left them with the spaces, as you can see.
By the way, if you're wondering why, if I want feedback, I haven't enabled comments to be posted on this site, let me explain: comments not only strongly tend towards the highly tangential, but often degenerate into abuse. One can see this on just about any website that offers readers a chance to comment.  If someone really wants to tell me (not the rest of the world) how he feels about my content, then he can send me a personal message via e-mail.  The address is toadsgoboad@gmail.com
