Can someone tell how you detect the tell-tale signs someone is interested in you (I mean in a intimate sense). For example, does this seem she is interested in him: He used to be her boss who hired her. (he is about 10 years younger than her) He left the company for another opportunity. He received the farewell party by all the staff (she was one of the organizers). He received a nice and rather expensive gift (which can be used in the business setting) from her. She invites him to a lunch at a high end hotel (and she stays at the same hotel for a night; she is staying there even though her home is about less than an hour by train/bus).
