And I can comment on whatever you say, since its on the open public thread...
This happens to everyone all the time..I can be posting directly to someone, and someone else comes along, and gets into the conversation...so what...I take no offense at that, since I realize my posts are fair game for anyone...
If I had wanted an absolutely private discussion with someone, I would have taken it to Private Freepmail(and have often done that, when a poster and I get into a discussion, which is often off track of the main subject of the thread)...
So, if you post on the open public thread, whatever you post can be commented on by anyone else...
Yes, you can butt in anytime you want, but keep in mind you can easily offend others when they are not speaking to you. It's all in the approach...
