i work at a local park as park patrol. i drive a golf cart around and make sure the parks r safe. im 19 and had a prime opportunity to get somewhere with a group of 3 attractive girls. me and my co worker/friend drove past them purposely because we knew they were taking pictures and my friend figured they would need someone to take pictures for them. they asked us to take a pic and my friend said he had a bad knew (which he did, he had a crutch) so he let me take the pics. i took 2 pics and got a little joke in there but as soon as they got what they wanted i gave back the camera and got back in my golf cart. i guess i froze up, i was a little nervous, but if they woulda started talking to me, i woulda been ok, i just couldnt strike up a convo. what should i have done?
