Mine actually happened the last weekend! The big first time.
So we had a class trip up to the mountains, we got there and a great friend of mine randomly goes like "Gerry, I have some weed, and (random name btw) Jenna (an actually 10/10 girl) has some too, and we decided to get high, do you want to try out?" and I was like "Stupid question, did you roll it?" but we had to wait till the dark. We actually did roll it, after hiding for like 1 hour because everyone was coming after us, and the guy with the weed, let's call him Fred, Jenna, an another hot girl, and another guy, Paul and I smoked it. Afterwards, we got to my room, swithched the lights off, and put on my favorite album, xxyyxx by xxyyxx , and everyone was lying on the floor, and I had a cute girl who was chilling on my chest.
TL;DR calm, chill and great!
