Affection has bad timing. It arrives while you're mid-sentence with the bank, or carrying something heavy, or three minutes from leaving the house.
Leaving room for it mostly means staying interruptible. Not endlessly available, since nobody is, but not so sealed into the task that a hand on your shoulder registers as an obstruction.
There is a small daily choice inside that. The dishes will still be there in four seconds. The person offering is offering now, and offers refused often enough quietly stop being made.
Put the plate down. That is usually the entire cost.
