first kiss
If the instances in one's life when their oral lips had touched another object with the intention of conveying a sense of love, or when another object's oral lips had touched their body with the same intention, were listed chronologically from left to right, the instance of the first kiss would invariably be on the far left of that rather sad and pointless list.
Her first kiss occurred just after she had been washed by the midwife and handed to her red faced mother.
