Hi, there, all depends.
My comment is old better than young. My Tse Tse is 24, very very bad temper and no manner, rude with big eyes and big teeth. Everytime when she is flat out, she is just like lion to roar. We are planning to fire her b4 her contract due, however the air ticket is over $1200 from now to June12. It is a lot of money to spend for her, 唔順氣!
