i am currently taking evening classes in business studies and there is this guy in my class who always stares at me during class. i usually ignore this and pay attention to my work. sometime last week he came over and sat next to me. i know that he talks to this girl in my class sometimes that i'm friends with so i did not switch seats. he asked me if i work at this place that's right next to where i work so i told him no i work at the place next to the place that he mentioned. after i told him he was askin me if he could come by my work so i told him that has nothing to do with me because i dont own the place. he just looked at me like he was confused. then he asked me wat my name was. i figured he wouldve found out from my friend anyway so i told him my first name. he kept asking for my last name but i didnt tell him. then he told me his full name. after that i didnt talk to him for the rest of the class. the next class which was two days later(last thursday) he told me that he has something for me and he would drop it off by the office. this was after class. i just said ok and left. then monday this week the secretary brought an envelope for me. it just had my name on it. it didnt have who it was from. when i opened it i saw it was from the guy and it contained a card and a love poem. i was really freaked out but my friend told me not to throw it away in case anything happens and i have to go to the police because it would come in handy. so left it at work. the next day when i went to class he was just staring at me and smiling. again i ignored it then he asked me if i got the thing that he send for me. so i said yes. and he said not to look so surprised. i didnt say anything. the next day, wednesday, as i was goin to work i saw him walking near to the entrance of my work place and he stopped and said hi. i said hi and walked quickly to work. then about an hour after i got a call at work and it was him. he said that he was just calling to say hi. so i told him that i do not appreciate him calling me and i do not appreciate him sending anything for me because it think its creepy and i dont like it so he must stop. then he asked it i was scared which i though was a weird question but i didnt answer, i told him goodbye and i hung up. the way i talked to him was very firm and there was no indication that i was even shaken by it. i made sure of that. thusday he didnt come to class. today i didnt go to work but when i went online my friend told me that he had come by my work. she said that he said that he was there to ask my boss about specifications for a computer but she thinks that was just an excuse. i just want to know what you guys think i should do because i really dont want this to get out of hand. i was thinking about buying a stun gun or pepper spray just so that i would have some sort of protection because class usually ends late and i have to wait on a bus to get home since i do not have a vehicle. do you think i'm being paranoid? what do you think i should do?
