Search Results: first impression on people

I've always found this a rather perplexing issue.

One type of girl will only date people after she's interacted in a casual group setting long enough to become good friends. She will usually get uncomfortable when a guy she's just met shows romantic intentions. She believes a guy who is worth her time can wait patiently while she decides how she feels about him through the course of friendship.

Another sort feels the opposite. She gets turned off by men who like her, but guard their intentions under the casual guise of friendship. She might say that any man worth her time will show how serious, dedicated, and interested he is from the get-go. She can become frustrated by a man who is subtle or cautious in showing romantic interests instead of "manning up" and showcasing his intentions as soon as he is aware of them.
