Hey sunbug (and anyone else reading this),
Just a helpful hint. When you want to reply to a specific post, look at the tiny menu across the top of their comment (with words like “Reply,” “Report,” and “Quote.” Click on the word “Reply,” and your response will appear, slightly inset, directly beneath their post.
Otherwise, your comment appears at the end of the entire page of comments, which can be confusing not just to whomever you are responding to, who then might not know nor ever notice you have replied, but also for anyone reading the conversation from the beginning (difficult to tell what post you are responding to, which makes the complete conversation a touch disjointed).
If, on the other hand, you aren’t responding directly to anyone, but just adding your own thoughts in general for everyone, then posting the way you have been works best in that circumstance.
