What do you think about me judging my sister for getting pregnant after she mentioned going to college
That's insensitive to do. Can you avoid being judgemental at this time?
No, she actually has lied to me many times
Your sister talks about something and does another thing, but she probably didn't plan to get pregnant either. Things like this happen often, be a good guy and help her. For now if you judge her too harshly it will only create chaos in the family that you don't need.
Oh sorry I didn't realize how other people's problems can be annoying. I will help her.
It's not your place to judge anyone else's life choices. You should just be supportive towards your sister and show her compassion.
