Confused about S

Am i going crazy??? so this is what u need to know: the lunchroom is on the first floor and the English class is across from it, the library is on the second floor and my L.E. class is on the third floor. I always go to the library during lunch time and S is in lunch. So wen the bell rings, I see S outside the library but the thing S has english after lunch. So y is S in the second floor wen he has english and its across the lunchroom???  can some1 explain this??? am i really going crazy???.........................................................  So after i went outside the library i saw S, i was holding a pencil so i stuggle to put it in my bag, and i turned around, S was right behind me and he said 'y did u turned around, i was going to scare u or tickle ' and i said ( which was true) 'idk' , and we talked about something but i forgot wat it was. Then in gym class, their was a person i knew next to S and i said hi to her and S said ' oh and i dont get a hi?' and i said ' oh,-_- . .. hi :D' . i really like my outfit today, its really awsome. and watim wearing 4 my necklace ( 'Best Friend' penguin mood necklace) and my earings ( new earing i just bought).  during the changing of the periods, i was so shoked and skipped a beat couse i saw S after talking to a friend O.O  i like turned and BAM he was thier , in front of me, i got scared.  and in class, i corrected i guy i think and he turned around with his had in front and i got got so scared that i almost fell of my chair , ( dont laugh) and he only wanted a handshake,..... a HANDSHAKE!!!! so i got scared over a handshake!!! do u know how much people was laughing at me,      so yea, im kinda down couse nobody patted my head :( . 4 many girls, they dont like it wen poeple touch their hair but its not 4 me , in fact i do the complete reaction, ( but it depends on who it is, like if a adult all of a sudden pated my head and i dont know him, ill be f*cki=*ng scared , but if it was like someone around my age and regardless weter i know him or not, i get happy,    i like peing petted like a dog, idk y , i just do). this week and next week i hv so many test coming up   T_T
