When word “Sorry” takes place

Situation I (via SMS)
Her: Where are you?
Him: So sorry, I’m busy, can’t call or SMS you.
Her: Ok (sigh..if it can be expressed through SMS..)

Situation II (via SMS)
Him: So sorry dear, I’m busy, please take care of yourself
Her: K (again she sighed!)

This is really occurred, incurred by man to woman relationship!
• Why man never understood woman’s feeling when she really needs you to hear her mourn?
• Why it is so hard for a man to just say ‘hi’ for his girl even he is busy in his career?
For man..Please think of it

p/s: she never wanted a ton of gold to be delivered to her home, bunches of flowers to be sent to her front door, but consider a little time for her to know you better.
Because “SORRY” is not a right word for you to excuse yourself from being not guilty and hold down on your words because talk is cheap actually.
