Sorry for the multiple msgs. My iPod is kinda jacked up. And if you aren't Irish, there are many places you can brush up on your slang!
So I checked out your story! It was really good, but the ONE thing you need is to convince me that.... Uhhhhhh.... Whatshername is Irish. I may be Italian but I was born in America and in order for it to be believable you'd need to incorporate a lot of compounds, Irish slang, an probably a litte bit of Gaelic. Oh! And as you saw above, make the two characters distinguishable from one another. The only time I realized the character change is when I saw their names. I felt like they had one personality. It's a lot for me to be able to say for three chapters, but I have a sense for these things. Otherwise, it was amazing! Keep writing,
