Final answer:
When a guy says 'cool' regarding someone's appearance, it does not necessarily imply attractiveness or lack thereof, as the term can have various meanings.
Step-by-step explanation:
Interpreting someone's response to your appearance, like when a guy says 'cool' in reaction to what you look like, can be tricky and does not necessarily indicate whether he finds you attractive or unattractive. The word 'cool' can mean various things based on the context, tone of voice, and body language which accompanied the statement. Since communication is multifaceted, the word might have been used to convey a casual acknowledgment or a mild form of appreciation without going into deeper expressions of admiration.
Moreover, attractiveness is subjective, and different people have different preferences and ways of expressing their opinions. Consequently, if someone says 'cool,' it could simply mean that they are comfortable with how you look, or they might not know how to express their thoughts explicitly. The usage of the word does not provide enough information to gauge a person's perception of attractiveness accurately.
To delve deeper into someone's opinion, it is usually more helpful to engage in a more extended conversation or look for additional cues in their behavior. Focusing on self-confidence and how you feel about yourself is also essential, irrespective of others' opinions.
