The context of the following conversation is Jan went home and changed. But she had to wait until her work was completed.:
Jan says I spilled ink on my new pants..
The friend responds Were you able to wash it out?.
Jan responds Yeah, eventually, but I was going out after work so I had to go home and change..
The friend responds You left work to go home and change clothes?.
Jan responds Yes, but I waited until I finished my work and skipped my lunch break so I could go home a half an hour early..
The friend responds That was smart. So you can still make it to your after-work event on time..
