Your reply is completely uncalled for. I hope you're able to get professional help for whatever it is in your life that drove you to be this callous toward someone.
It can be really hard to understand why people do what they do. But I do know from personal experience that shelter insecurity is one of those pervasive stressors that makes everything difficult.
Maybe their phone getting screwed up was the proverbial last straw. Now, instead of a calm, considered approach, they're fighting exhaustion and panic while trying to problem solve.
But no matter what their circumstances, being vile toward them is unwarranted.
