Men will say, "I'll call you. I'll call you." When they say they're going to call, they don't, and when they say they're not going to come, they do.

The remark wryly observes a mismatch between what people—specifically men, in the speaker’s framing—say they will do and what they actually do. It points to the social habit of using promises (“I’ll call you”) as polite placeholders rather than firm commitments, and to the unpredictability of attention and pursuit: declarations of intent can be performative, while real actions may arrive unexpectedly. The quote also hints at a defensive realism learned through experience—trust behavior over assurances—and at the emotional whiplash caused by inconsistent communication in relationships. Its humor comes from reversing expectations: stated plans fail, while stated refusals sometimes turn into appearances.
