Who is Mrs. Milagros from Rosaura a Las Diez and what is their importance?

Mrs. Milagros is a widow. She has three daughters and supports her family by running a boardinghouse. Mrs. Milagros is described as talkative and kind-hearted, but she is not always sensible and definitely lacks tact. Mrs. Milagros favors Camilo, and at times we suspect that she might even be a little in love with him. It is obvious, however, that her attention is more motherly than anything else.
