I'm not going to let my homeless sister stay with me.
Why won't you let your sister stay with you? That's really mean!
I don't want to be seen with a homeless person.
It's hurtful not to help a homeless family member. You shouldn't be judgmental and help your sister out without worrying about what it will look like to others.
It doesn't matter, I am the one who is hurt by this.
No, her not having a home is the one who is really getting hurt. It's dangerous outside and you need to be more considerate and show more compassion.
