Tardiness

To be honest, I am late most of the times unless it's a very important meeting or an appointment. This might sound strange, but, I believe being 30/40 minutes late to a wedding or an informal gathering is acceptable. I think arriving later than the time appointed is the way of Southeast Asians. However, in more formal situations such as business meetings or medical appointments, tardiness is intolerable*.

*Intolerable is colloquially used for things that are unbearable or are extreme hardship. I think unacceptable would be a better word choice, but intolerable could work
