Blogs are kinda like self-checkout at the grocery store — the machines are different from store to store.
If you want to comment — and I hope you will — just look to the little box to the left of the post, where the date is. Under the date, you’ll see “0 comments” or “86 comments” or whatever. Click on “comments,” then scroll down to the bottom of the post — you’ll see a box for leaving a reply.
Thanks!
