Here is a speaker caught in the nervous seconds before he might kiss someone. The poem is a list of symptoms: sweaty palms, a racing pulse, a twitching foot, a stumbling voice. Each line adds another sign of panic, so the reader feels the tension build the way the speaker does. He worries that he is moving too soon, that he will make her uncomfortable, that she will turn him down.
The refrain "Not knowing what I should do" returns three times and shows how stuck he is. Midway, he imagines an easy way out: a "magical connection" where both of them turn and kiss at the same moment, with no risk and no decision. The ending suggests this wish is also a kind of hiding place. "Never wanting to make her uncomfortable" sounds considerate, but the speaker calls it an excuse. The mood is anxious, awkward, and a little funny, and it ends with him still sitting there, thinking and not acting.
