Do you ever cut conversations short and later regret it? (person, attractive)

[The Postman]

Like say you've met someone randomly somewhere and get into a conversation, and say you might like this person, but you somehow feel awkward prolonging the conversation too long or feel you're imposing, or you might not know exactly what to say, so you quickly say, 'oh I have to go' or make an excuse, and later regret it? Has that ever happened to you? I sometimes feel if I'm talking to an attractive girl, or an interesting person, it could be a chance to get to know this person, assuming that they have the time etc to spare.

I have kicked myself for cutting short a conversation for the reasons you describe many times. I guess I must be just insecure enough to feel like I may be imposing on someone's time or that they may not be enjoying the exchange as much as I am. I can be clumsy with social etiquette at times and prefer in the moment to err on the side of caution. I have sometimes wondered later if I screwed myself out of a potentially cool friendship by my decision.

Another case where cutting a conversation short has been a regret later on is when I had more information to impart to someone I know but decided to wait till another time, for some reason. Sometimes you only have one chance, and incomplete information can cause myriad problems, practical and personal. I especially regret it when I do this out of general sheepishness or fear. My holding back doesn't always save me from negative consequences. Sometimes it makes things worse.
