Strange/probing call..........seemingly interested in answering ad, but spends entire time being too inquisitive-never committing. Calls back more probing........seems to be on a quest to collect information from whomever answers the phone about his primary interest. Don'tknow who he is! Feels disturbing like somethings not right, even though they try ( perhaps to hard) to be affable. This hasn't happened alot,but enough not to want to hear from this individual again, just a sense- and knee-jerk reaction perhaps.Hope I'm overreacting. Still-Gonna block this number.
