同事問我生日日期，但最後不了了之

It sounds like you are feeling hurt and confused about a recent interaction with a colleague. It can be difficult when we feel like someone has dismissed or ignored us, especially when we were vulnerable enough to share personal information like our birthday. From a Buddhist perspective, it is important to remember that all beings are inherently interconnected and that we should strive to treat others with compassion and kindness. However, it can be challenging to do this when we feel like we have been wronged. From a psychological perspective, it might be helpful to reflect on why this interaction has affected you so deeply. Is it because you feel like your colleague doesn't value you as a person? Or is it because you were hoping for a closer relationship with them? Regardless of the reason, it's important to remember that you are not alone. Many people have experienced similar situations and it's okay to feel hurt. If you feel comfortable, it might be helpful to talk to your colleague and express how their actions made you feel. They may not have realized the impact of their behavior and could apologize. Alternatively, it might be helpful to focus on building relationships with other colleagues who do value and appreciate you. Finally, from a coaching perspective, I would encourage you to practice self-care and self-compassion. Take time to engage in activities that bring you joy and remind yourself that you are worthy of love and respect.
