Women love confidence and a strong male presence. Women like to be approached. If you are to be in charge of the household, then you best take charge and approach a woman of your choice. So you get turned down? Who cares. But then you may not get turned down.
I am talking to you like the 37 yr old man that you are because I know you can handle a frank discussion. Take charge. When the time comes and you are attracted to a woman, then approach her and compliment her - but honestly, forget about women that are interested in you. Focus on the woman that interest YOU.
Whoa! Hold the phone! There is a way to approach a woman, though, and there is a way NOT to approach a woman.
Do NOT approach a woman unless she has given you permission. Meaning: If you see someone you like, don’t ever just approach her out of nowhere and start talking to her. That will give most women the creeps, like you are a stalker. You have to wait for the subtle permission signs.
Eye contact.
A smile from her.
You say “Hi, gosh, it’s rainy. Let me get that door for you.” She smiles and says “Thank you.”
One time I was at the post office, and I smiled at a guy who looked familiar. I asked him if he was from my hometown. Seems I made a mistake. I politely wished him a nice day and conducted my business. Went out got in the car. Pulled out of the parking lot. Became aware he was pulling out behind me. He followed my car two miles down the road to a Blockbuster. I went in and could see he was parked in the parking lot waiting. I went next door to the grocery store. Did some shopping. Went around the corner from the bread aisle and he was STANDING RIGHT THERE. Eek!

I made a joke about running into him again and went through checkout and got in my car and took a circuitous route home and lost him.
That is how NOT to interpret a woman as being interested.
If she smiles, lingers when you talk to her, any woman that consistently tries to sit in a desk near yours (I see you’re going back to school) or starts conversations with you, or walks with you to your next class may be interested. The best way to know is to talk to her. And if you like her, write down your email on a piece of paper and give it to her and tell her to drop you a line sometime. If she does, that is a clue she wants to get to know you better.
