I know right?! How dare she want help from her husband after buying the groceries and walking with 3 heavy bags at least halfway to their house. Divorce her!

Could have been that she asked him to meet her at a place halfway in-between and he thought he was being invited for a meal or a drink there. OP's kinda vague on the subject but there's no reason to think he knew she was coming home from the supermarket, that's just what turned to have happened.

For her to wait at the supermarket and call you to use the car to pick her up? If you have three heavy bags, don't start walking and subsequently get angry about the bags being heavy, you can't have it both ways...

Have you never bitten off more than you could chew and had to ask for some help?

Was legit about to comment that...this fml doesn't give much info. Was he trying to surprise her WITH something? And how far was the halfway point? Not much I'm guessing if you were able to walk..

OP said that he tried to surprise her by getting there quickly.

I was going to say the same thing. And surprising her by getting there quickly makes no sense. That wouldn't surprise me, it would make me happy. Though it's worth noting a vehicle would have been even faster.

I think it's pretty common sense. It's either that or she's just chilling on some random street corner for no particular reason.

It's the norm to walk to and from places in Europe, so it makes perfect sense that she walked. It's possible she underestimated her ability to carry it all. It happens sometimes.

Right. Remind me, if ever we get married and I go shopping and find something you've been wanting for ages but I already have as much as I can carry, you won't want to help carry the groceries so I should just not get that present for you.

I'm not entirely sure you understand the word "reasonable," then.

but since his wife asked him to meet her surely it's a bit stoopid as well as being cute?
