No, but you also don’t have to go out of your way to be intentionally hateful and malicious.
Her “concerns” could have been addressed in a more dignified and mature way. Simply tell the family that you would appreciate it if they could try to calm him down when he begins to get too loud bc your children don’t understand and get scared. Then politely suggesting the alternative locals. That’s it. Her only problem was the noise. Everything else she wrote was intentionally antagonistic and uncalled for.
I’m not saying her concern was even valid, but there was a MUCH better way to go about it than this ugly hate mail.
