1, Bruce Lee may show confidence and calm, and handle this situation in his own way. He may try to clean his socks himself, or remind Blair of this without hurting his face, and he won't pay too much attention to the small details of this matter.
2. Bruce Lee may feel a little embarrassed and uncomfortable, but he may also feel that this is a trivial matter and it is not worth affecting their relationship. He may choose to put it down and continue to concentrate on learning boxing skills.
On the other hand, if Bruce Lee has a strong paranoia about health and a tendency to pursue perfection, he may be dissatisfied or angry with this situation and may ask Blair for compensation or an apology. However, this reaction may also be inconsistent with Bruce Lee's personality and lifestyle.
In a word, Bruce Lee's reaction depends on his personality, life experience and views on this situation. As this scene is fictional, it is impossible to draw a concrete conclusion.
