I was sssooo happy but then I came around the corner me my friend sam and my other friend breanna we were all giggling and then he look upset so he turned to me and said… “I’m sorry sydney but it’s over” then he emails me when I get home saying he didnt want to break up with me but he heard somthings and so I said…”what was so important that you had to go and break my heart?” he replied “well it is your chose to not forgive me and it was my chose to break up with you so get on with your life!” and I said “I have you idot!!! Dont eva email me again!!” so he didnt but all day he has been staring at me with like these googly eyes and I would stare back with a bit**y face on. Why did he do this??
