Changing Times

My phone was buzzing on my bedside table, i have no reason to get up after all it was a Sunday and best of all it was my birthday so i could do what i wanted, i was 17 today and life was pretty sweet for me at the moment i had a girlfriend college was going well, nobody hated me, i decided i would look at who was calling me funnily enough it was gemma my girlfriend so i decided ide answer, "hey beautiful" I said,
"I'm Not" she replied,
"ha ha you are to me darling"
"yeah whatever, anyway what you up too later on?"
"um... Nothing why?"
"Well it is your birthday Dumbo so you wanna go out somewhere?"
"sure, come round in about an hour"
"okay, happy birthday, i love you"
"i love you too cya in an hour"
"bye."
The call ended there and i decided i would get up and have a shower, as i waited for the shower to warm up i checked my messages, 10 new messages my phone displayed, a sat down on my bed all of the messages were from friends wishing me a happy birthday, the shower began steaming so i walked towards it and caught a glimpse of my self in the mirror there was something unusual about myself, upon closer inspection i noticed 3 claw marks on my abdomen, this was strange i had absolutely no idea how they got there, i shrugged it off thinking it was dirty or something and got in the shower then got ready to go out.
