Whether a girl saluting you is enough or not depends on the context and the relationship between you and the girl. Saluting is a gesture of respect or acknowledgment, and its significance can vary based on cultural norms and personal connections.
If you're in a formal setting or a context where saluting is a customary display of respect, then it might be sufficient for the situation. For example, in military or uniformed service environments, saluting is a standard way of showing respect to superiors.
However, if you're in a casual or personal setting, a simple salute may not be enough to convey more nuanced emotions or sentiments. In personal relationships, people often seek more meaningful ways of connecting and expressing emotions, such as through conversation, gestures of kindness, spending time together, or showing affection.
The appropriateness of a salute as a gesture of respect would also depend on the nature of your relationship with the girl. If you have a close, intimate relationship, a salute alone might not be sufficient to express deeper feelings or emotions.
Ultimately, the significance of a gesture like a salute depends on the specific circumstances and the emotional context surrounding it. It's essential to consider the individual and their preferences when choosing how to express respect, appreciation, or affection in a given situation.
