I'm very close to my hubby and we talk about pretty much anything that's on our minds. I'm not much of a talker though, even when I'm with him, but that's just because I don't feel the need to talk much in general.
I have one friend who I only meet around once per year (she lives far away), but when we do meet, we usually talk non-stop for hours. Few people can get me to talk as much as she does.
I'm not close to anyone else. I used to be close to my sister, but we've grown apart from each other in the past few years. When I'm with other family members, I try to talk a bit, just for them, but I don't share much with them or feel close to them.
With other people, I rarely say anything at all unless I need to for practical reasons, or if they start talking to me. I know many people find it strange that I'm so quiet and can go through the whole day without talking, but that's just the way I am.
On the rare occasion that I start talking really a lot (which is usually with my friend mentioned above), people literally stare and go speechless, because they realize they've never heard me talk like that before, even after knowing me for years.
