A little long as I want to include some background.
We've recently had a new family move in next door. Mr X (the DH) has a car business so the first week they moved in there were 4 extra cars in our narrow little cul de sac, all parked legally, 2 on our shared driveway and 2 more or less outside his house. We have 2 spaces for us on our drive so no issue with us not being able to find parking, just a little extra manoeuvring needed as one of his cars was parked across his drive so blocking ours by a few inches. This bothered DH a little but I told him to leave it as they were new neighbours and I didn't want any issues. We could just park right up against the wall to allow space for us to get in on the driver side.
When bin day arrives they constantly put bags in our bin and leave bags all around the side. DH went out once to put a bag in our bin and there was obviously no space! There's only 2 of us and 6 of them so I again I told DH not to bother saying anything, if our bin is half empty their bags going in isn't an issue and they would obviously have more rubbish than us as there is more of them. They obviously hadn't realised we had more bin bags that time as our bin had been taken out and put in front of the house.
Today DH comes home from work and there is vomit on our empty side of the drive and on theirs next to the driver side of their car. He knocked on next door and asked if everything was ok. The wife answered and asked why he was asking this, he said there is vomit on the drive. She said let me go in and check with my husband and closed the door on him. DH waited a few minutes and realised she wasn't going to come out again. He then parked elsewhere. I arrived home and the wife was washing vomit off the drive. I was unaware as to what had happened and as soon as I opened the car door she walked over and told me DH was unreasonable for knocking on and he should have just cleaned it himself. I asked if it was my DH's vomit and she said no it was her DH's but he was come across with nausea, puked, walked in his own house, and didn't tell anyone. She said it had just happened so her DH didn't have chance to tell anyone. I enquired about her DH, hope he got well soon and just walked in to my house. Myself and DH checked our security camera and Mr X had vomited at 2.25pm, myself and DH both arrived home between 5 and 5.30pm so it was there for hours! I said hello to Mrs X just now as I was taking my bin out and she said 'I thought you were nice neighbours but I was obviously wrong' and just walked in to her house.
I'm so confused, did DH or I do something wrong here?
