Never On Sunday

The speaker welcomes affection on almost any day, but firmly reserves Sunday for rest. The repeated lists make the invitation sound cheerful and playful, while the repeated exception gives the song its central joke. The emotional movement is simple: open-hearted flirtation is balanced by a clear personal boundary.

The many kinds of days—cool, hot, wet, grey, or payday—suggest that the weather or circumstances do not matter: the speaker is willing to be kissed whenever, as long as it is not Sunday. “Be my guest” is a friendly idiom meaning “you are welcome to,” not a literal invitation to visit. “My day of rest” explains the exception in plain terms and makes the boundary sound reasonable rather than rejecting.

The tone seems teasing rather than serious or angry. The speaker’s repeated “never ever” sounds emphatic, but the surrounding invitations show that Sunday is the one protected day, not a sign of lost interest. The song does not explain why rest matters so much, so listeners could imagine a practical or personal reason, but the lyrics leave it open. Its humor comes from treating a small, ordinary preference as a firm rule.
