Dr L: She is thai and I can tell you that with her the case is that she just loves relaxed low-key places. A beach is what she prefers the most and we have over the years been to many very secluded places - where we actually were almost all alone - and loved every second of it! She is not from the "industry" -- and do not like to hang around in bars etc. Ok with me - that I can do at other times!
