conv: my sister planned a birthday party for our mother on a day and time in which it will create a huge hardship on me. She knew my schedule when she made the plan. My mother will be 85 in a few days. My sister planned a surprise party knowing the day_comma_ hour and location would be very difficult for me to attend. I hope you make it. Thats a big birthday. It is day after tomorrow and I am still not certain I can work it out. Sometimes people are very inconsiderate. That not good. Maybe she will understand if you just can't make it.
