I have a friend from England. When we chat I often start speaking with an English accent. It's a good thing that she knows me and my quirks well enough now that she doesn't feel like I'm mocking her. When I call her she often thinks I'm her sister....who is English and has the same name as me! So, I guess I'm pretty good at it. Yay me!
If I chat with someone from Australia, New Zealand or even Jamaica I have to concentrate really hard on not falling into using their accent. I'm just an accent sponge. But, I'm picky. When we lived in the Philippines I never talked Tagalish (mixture of Tagalog and English). My grandmother and great aunt were from Finland, I could mimic them, but I never had to fight myself from speaking with that accent. I did love the way my grandpa talked...he was Norwegian. I would love the way he would call my brother, Michael, "the boy." I always wondered if he knew my brother's name. My Mom was Lin-nee-ah and I was Katrin. My Mom's name is Linnea (pronounced Linn-ay-uh) and I'm Kathryn (pronounced Kat).
Maybe when I grow up I can be an English Lady. Lady Kathryn of Lesbian.
