A childhood belief about periods

When I was young about 7 or 8 I was told what a period was. So the day after my 11th birthday I had to spend the weekend at my dad's house ( my parents are divorced ) well I was in my bedroom laying down on my bed and I seen the blood. I wasn't scared cause I knew what to expect. So I yelled for my dad and he came in and seen the blood and he thought I was dying. He was ready to call 911. But luckly I claimed him down and told him just to call my mom and to tell her I started my period. Well he called my mom and said "Um Shirley your daughter has started her um um um um period and um can you PLEASE come over NOW"!!! So my Mom comes and my dad is freaking out. So she came into my room and said "Congrations you have started your period so get use to it cause it'll be with you for along time". Well she talked to my dad and come to found out my dad was always told that a woman has a monthly vistor rather then the right word PERIOD. That is why my dad freaked out cause he never heard of it being called a PERIOD. And what was even worst my mom wouldn't let me come home she made me stay with my dad for a full week with my first period and my dad would have to go with me to the Drug store to buy pads. Thank God he knew what those were LOL.
