Still, when the Sun and Moon are in trine it can bolster the sense of well-being between the masculine and feminine parts of the personality.

Serial killer Myra Hindley was born with Sun trine Moon, and she had a grandmother who adored and spoiled her. Hindley directly helped her partner Brady in his killings of children, and played a supportive role.
Their first victim was 16-year-old Pauline Reade, a neighbour of Hindley's who disappeared on her way to a dance in Crumpsall on 12 July 1963. That evening, Brady told Hindley that he wanted to "commit his perfect murder". He told her to drive her van around the local area while he followed behind on his motorcycle; when he spotted a likely victim he would flash his headlight, and Hindley was to stop and offer that person a lift.
Trines always naturally find ways of bringing harmony, accord and agreement, and the individual feels at home with themselves. Sometimes this can be challenging when the marriage is in trouble and the native sees no problems and expects the partner to always maintain a helpful and supportive attitude, so difficulties have a tendency to escalate.
In the book Cosmic Marriage there was an example of a man who has Sun trine Moon which is also square Uranus. The man had two successive marriages and each wife left him because he spent too much time away from home. So, if he didn’t see the problem the first time around, he has certainly been blind to it a second time. Consequently he is so comfortable with his lifestyle and doesn't feels the need to change and he cannot see a problem. Ordinarily, those with Sun trine Moon can have a natural way of being in the world, and the energy tends to flow smoothly.
