You better believe a woman know when temperatures are rising. When they walk into a room. Into a club. Into a bar. Even in the park.
She know when men are looking. Some know, what various men are thinking? Just remember, what you thinking can't get you in trouble? That's only when you speak. Or when you react upon that notion.
Yes, temperatures reaches higher degrees. When ladies comes around males. They might not speak it in public to create conflicts. But will discuss it behind their back.
Similar to things women do. When they see a man of interest too.
