I would appreciate a heads-up. The one that really frosted me was when our neighbors listed their house for sale. Mom worked during the day, and Dad's car was a mid-life crisis 2-seater, so when they got the call that a realtor was going to show the house, Dad would pack the daughter in his car and send the son to my house WITHOUT NOTICE and WITHOUT ASKING. That seemed to stop the day I had to take my son to soccer and left his son on his own doorstep.
