Be yourself and don’t play an act. Be honest and open, don’t hide anything important.
Of course there are many factors that may be important, depending on how, where and when you met under which circumstances and what your plans are.
Mr. ZeeTee only was honestly himself and caught me from the first moment we met in person - like no one else before, I was a bit more shallow with men before we met and I hope I’ll never have to go back there.
