Well, I love my partner, and part of that IMO is not sending him out in the cold at 10.30pm on a sunday for lemonade. If he offered to do a painkiller run - or if I asked him to - I might combine that with a request for a few nice bits that I fancied, but I definitely wouldn't send him out just for that.
Yes to this.
I have a friend who likes to make a big show if asking her DH to get her things from the fridge/kitchen/her handbag/the car/pop round the corner to buy x,y and z, when we are in each other's company. You can see the poor man getting more and more frustrated (5 separate runs out to the car on one occasion) as she sits there smugly smirking. It's like she is proving how under the thumb she has him. He should really just say no, but I imagine all hell would break loose and he wants to avoid a making a scene in front of people.
I wouldn't ask my DH for something I just fancies that late at night. I wouldn't appreciate it if he try and round to me and went "I fancy a sausage roll...would you please get me one from the nearest shop?" At nearly 11 at night, so I wouldn't do the same to him.
I asked him what he would do if I asked him what OP asked her DH.
He said he would 100% go out and get me sanpro/painkillers/nappies for the baby etc, but said at 10.30 at night, no he would not be heading out to get something that had just tickled my fancy.
He is away out now to get me some fizzy lemon water as all this talk of it has made me crave some, but it's midday and he was popping out anyway to get a picture reframed for my birthday.
