I cry more often than I'd like to admit and completely blame my moon conj. mars. It's in the 9th house. I have lots of squares and opposition to both. I mostly cry when I'm angry, it's like my body's natural response to release the excess energy. I hate it but it is what it is. Crying instantly makes me feel better. I even shortly forget what I was angry about. It makes me incapable of holding grudges. But then my other placements step in and I just ignore the offending person's existence as necessary.
