The definition of beauty "attractive" varies from a person to another. However, answering your question; maybe they were intimidated and scared they might be rejected. Or maybe they were looking for a quicker approach, assuming that a less attractive girl would be easier to talk to. Or perhaps it is just what avksxXXVII said! Who knows?
