Woman of a certain Age

So on another note. My period had stopped for five months. Just when I thought it was over bam it's back.
I also have peach fuzz on my lip and a little arthritis.
Why do people start treating you different when you become a woman of a certain age as Wendy Williams would say. Especially younger women. Is it they don't want to see where they are going. What will it be like when there kids are grown up.When they face menopause or a midlife crisis or their husbands midlife crisis.
For God sake I am still a woman, a wife a mother.I still enjoy going out putting on makeup bleaching my hair. I don't need to go in a corner and become invisible. I AM HERE.
