I only like Lilah. My least favorite of the four is September. C'mon, it's a Month! September? You could do better than that. Also, the Green Day song "Wake Me Up When September Ends". I love the song, but it wouldn't be good for someone named September to hear that. Just saying.
I know, I don't like the names either, I didn't get to choose ANY of the names. I do kind of like Lilah I guess... and I would like Mai if it was spelled May. I find the name September very ugly and I think Isla is overrated.
