So tonight her friend dropped her off, I was there and she called me to help her with a box of bottled water.

She said that she was going to put it in a shopping car unless( 2 seconds pause) you want to carry it upstairs. Of course I replied.

We went up to her condo, she was going to walk her dog, she got its leash and was ready to go out when I asked her if she had a pipe, she said yes and we smoke a bowl, have some small talk while we were smoking.

We were getting out from her apartment when the security guy was passing right by her door, the guy is cool with me because we smoke together.
She got very nervous and told him she was gonna hook him up with some bud.
i had some that she gave me when we were inside, and gave it to the security guy so we didn't have to go into her condo. She seemed relief and told me she likes my style. I guess it was the way I handled the situation. We went downstairs, we talked a little bit more and I got back to work and she went to walk her dog.

I know I could've got further but I just didn't see any chances to escalate or get closer to her without creeping her out.

All I got from this was she basically used you to move her stuff.

Go watch the opening monologue of Roger Dodger. You'll completely understand why she did what she did.

Also, you could've escalated things. You didn't. And she knows that you didn't because you were afraid of what "she would think". Basically, she will now think of you as the guy who's scared to take steps because he worries about other's opinions on his actions.

Be bold. It should always be the first duck you need to get in line when you're with women.

Boldness is rewarded like nothing else.

Also, why was she nervous around the security guy? I'm sorry but I couldn't see a reason for that.
