It's no bother at all !!!

Kathy	I'm calling to inform you that I'm resigning at the end of this month.
Rachel	Really ? What a surprise.
Kathy	I know. As a matter of fact, I'm getting married next month. My husband made a new investment in Shanghai which turns out to be a remarkable success. So we decided to relocate to Shanghai.
Rachel	Congratulations ! I am happy for you. I would like to send you a floral basket. Should I send it to your office ?
Kathy	No, its OK. Don't bother.
Rachel	It's no bother at all. I insist on sending my regards to you. It's nice working with you.
