Do people think about someone after they talk to them?

[sadavis00]

Basically, I want to know if a girl I speak to regularly thinks about me after I say goodbye to her. I usually assume that when someone goes out of my view, I am no longer an object of their attention and thought. It this a valid assumption? I usually think about the person I talk to after I talk to them, do other people do the same?

If they do, then do they conduct an inner articulated monologue, like "he's a nice guy, I wonder why he said that"? Or is the "thought" in question really just an unarticulated feeling like feeling of parting, distance growing as people walk in separate directions, not really "said", but just felt.

On related question, do people think privately about other people and the conversations they had with other people as the mood strikes, any moment of any day? Or does the saying "out of sight, out of mind" apply. I want to know because me and this girl remember aspects of our conversation conducted a week ago, how is it possible to remember something from such a long time back if the person had not thought about the conversation in the mean time to consolidate the memory.

I realize I could simply ask her "have you thought about me", but there are problems with that. I simply want to know if she might be able to think about me like I think about her, at least in the form of her thought, if not the content of ther thought.

Simple answer is, yes, of course they do.

Think about how you think. When you have a good, close conversation with somebody (or the opposite of course); that person is almost certainly on your mind after you say goodbye, even if it's just for a few moments.

A week isn't a long time in terms of memory.
Especially is it isn't raw data but a conversation with idea that are linked together.
If someone doesn't remember at least a bit of a conversation I had with him a week ago I think that the person didn't listen to me in the first place.
