Here's something I read somewhere and what I'm trying to adopt: it's okay if you're bringing it up to explain/warn people of something but not to excuse yourself (i.e. you'll keep working on it and it will get better as time passes, if slowly). I think what you're doing is all right.

But I also think depending on how you said it and what the other person went through (i.e. how something like this would sound to them) a lot of things can sound different.

If something is really important to you and someone doesn't like it it probably just says that you two don't get along well just as you are? There's probably a story behind why you have this habit of explaining this thing you've got. You obviously did this to say that you're not talking over her because you don't care about her. I know if I do something like that there is always a story behind it like I got hurt myself in a similar situation where I could have felt better if the other person explained this, or I didn't use to do this and I hurt someone, etc. Dunno what it would be like if you're just sweet like this (and this is really, really sweet) but there must be a story too--you might consider telling it. Also good to ask the other if there's a story behind their reaction.
