The context of the following conversation is Robin recently had an operation and had been recouperating at home.  Robin decided to go out for a walk but quickly became tired.:
Robin says I tried to move around a bit more today and failed miserably..
The friend responds What did you try to do?.
Robin responds I just wanted to go for a short walk, but not a minute after I started, I got so tired and winded. And the pain got worse..
The friend responds Oh, wow. Well it was really an extensive surgery you had. Maybe take it easy until the doctor actually tells you that you can start walking again. It's way to early and you shouldn't be pushing yourself like that..
Robin responds I know, I regret the attempt but I was itching to get outside again!.
The friend responds In time, Robin. In time..
