Favours

How is it pos­si­ble?
He offers to go out of his way, buy the thing from me, and make me feel like he is doing me a real­ly big favour, when he real­ly should have picked it up a week ago, I’ve had to pay extra just to get it in for him, and now I’ve got­ta stay back late just to get this all tak­en care of once and for all…
And some­how I still end up feel­ing like I owe HIM one.
