...It is like buying a house next door to a race track or concert venue, then complaining about the noise.

If the property across the street was zoned commercial, her property would have been priced taking that into consideration, and she should realize that she may not like whatever business was going to occupy that commercial lot. And if she didn't know, her beef would be with the seller or RE agent for not disclosing that.

Bottom line, while you may have a beef with the funeral home, is is rude and disrespectful to attempt to disrupt a funeral service. Hope she realizes what goes around comes around.
