Ooh! I like it, in an *almost* guilty pleasure kind of way. It's almost unheard of where I'm from (except one of my friends had a cat named
Tamsin, but he sometimes shortened it to Tas or
Tin, which is really cool... well for a cat). If I met a
Tamsin, I imagine she would be independent, artsy, hipster-cool.
Tammy is ucky and 80s to me. And I don't like
Thomasina. I think it calls for a romantic middle name to make it that cool punk-hopeless-romantic character that we see in the movies.
