Think it's a really good idea to have female friends (as long as you aren't really needy and just got LJBF'd by her). Hanging out with hot girls while out at night brings instant social proof, and makes you safe as well as making the girls around jealous and therefore competitive and want you even more. That's the crux of the #1 PUA in the industry right now AFC Adam, he brings a hoard of girl FRIENDS out w/ him and just basically grabs whoever he wants and f*cks them. It's just that easy. In fact I think that it's SUCH a good idea that I would even encourage people to go out and be afc to some of the hottest girl groups you can find, JUST to go out with them as friends later so you can f*ck other really hot girls. It makes cold approach pickup like 10 times easier. Trick is you need to be strong enough and have enough abundance of women in your life that you actually can treat them like friends, and not NEED to bone them. Just don't get sucked into that chasing the friend because you SUPER LOVE HER trap.
