If a girl has cut marks on her wrists, she self-harms and WILL be an emotional drain at least, or a death threatening crazy girl at worst. Lately, girls have started realising that guys KNOW this Red Flag – so they have now started cutting themselves on the inner side of their thigh – and even their breasts – so by the time you find out she cuts herself – it’s already TOO late. AVOID these girls unless you fancy regular suicide threats and frantic calls from her friends and family.
