My Papa's Waltz by Theodore Roethke The whiskey on your breathCould make a small boy dizzy;But I hung on like death:Such waltzing was not easy.We romped until the pansSlid from the kitchen shelf;My mother's countenanceCould not unfrown itself.

The two most important elements in establishing credibility are expertise and trustworthiness

Credibility is subject to change over time

What will compromise your credibility in the short and long term?
