Doesn’t matter if girlfriend’s/wife’s friend is gay, straight, female, male etc

1 - You don’t discipline another’s child - wrong.

2 - You don’t fix things in another’s house without asking or discussing first - disrespectful.

3 - If being picked up from the airport everyone should know beforehand - bad comms and disrespectful.

4 - This applies to both parties. 

 It’s called “boundaries” and sometimes needs to be overtly laid out and communicated.
