Not so Well-suited

As Gobby and Billy Idle prepared for their impending trip (quite timely for them with a week still to go) Gobby returned home to find two spanking new suitcases awaiting her.

Looking them over she confirmed with Billy:

"I take it the one in your favourite shade of blue is yours and the only colour left over for me was bright orange?"

To which Billy explained,

"I was going to get two the same but they'd get muddled up."

To which Gobby felt the need to expound,

"But we'll be staying in the same room."

And didn't entirely concur with Billy's wisdom of:

"That's not the point.  If I lose you I want my own stuff!"
