Or to ask them to let me know if they're going to do so?
DS`1 has severe allergy to grass pollen. On Tuesday he had a reaction despite being indoors, with doors and windows closed, to the neighbour mowing the lawn. It seems more severe in the evenings. He had to go to the OOH GP and had a day off school due to the swelling and wheezing.
I don't know if it's overstepping the boundaries of neighbour though. Also, he's a big drinker, and I find him very intimidating.
The neighbour was here last year when DS1 had an attack that required an ambulance - again, it was evening mowing that triggered it. Neighbour knows this.
Really, WWYD? I feel that asking would be horribly U, but it's not very fair on DS1 to have time off school/ frightening allergy attacks either.
