Dear...
Later I might leave office earlier for the checkup...
Since afternoon I don't have much things on hand I need to work out immediately, I might as well go get my test done and return back to JB...
Do you have anything urgent in the afternoon that you need to settle?
If not, wanna meet up after my checkup and we make our way back home earlier?
We can avoid the jam and perhaps we can dine out together tonight...
What say you?
