A week ago this boy in the lunchline was playn around, he taps me so I turn around and points at the guy behind him and mouthes,”he likes you.” A few seconds later, he asked me how old I was. Then the next day he says hi to me eveytime he saw me in the hallway. That same day when I walked into the cafeteria, I heard someone scream “aye girl”, so I turned around and he said hi. So then he stop saying hi to me for like 3days. then on tuesday he was walking with his gf(i think is his gf) and I was walking past him and then I felt someone tap me, and I turned around and it was him, and he paused and waved, so I waved back. Then I saw him in again friday in the hallway and he reached his hand out so I can give him a high 5. Then, when I was in the lunch line he taps me and asks me can i get him some pickels. So I give them to him and he says ‘’love you’’ and walks off. I thought this was weird because Im new, and I dont even know him .The day before yesterday in the lunch line, he tapping me and asked if i was ticklish. A few seconds later he tickels me.Then he says,” your 14 right “. yesterday he reached his hand out to shake mine, and he wouldnt let my hand go for 50 secs. Then he came behind me and said he was my bodyguard and if anybody ran up on me he said, “f *off” in a deep voice. Then he started teasing me and saying my head was big. Today I was walking in the cafeteria he was sitting at his lunch table and I was walking by, and he screams,”big head,” so I turned around and he says”love you”. When it was time to line up for lunch I ‘m in the back of the line and he comes all the way to the back to talk to me/mess with me. Then he started tickeling me from behind and I tried to grab his hands to stop him and he starts holding mine from behind. Then the lunchlady says”is there some flirting going on in my lunchline” then he says” I dont know, you tell me”. I went 2 the bathroom, so when I got back he called big head, I turned around and he winks at me.
