Her hair, like golden silk, flows elagantly as the breeze weaves thew it., Her ruby lips, softer than an infant, yet so intimidating. Her eyes, as blue as an unpolluted atmosphere.

Explanation:
The word "at" refers to a specific time or location. In this context, the speaker is certain of when he will be finished, therefore to show the certainty, the word 'at" is used.
Likewise, the word “about” is used to denote an approximate time or location. The speaker cannot give an exact time when he will get home. He can only give an approximate time.
