Which type of questions do you prefer personally?

For me it is a sharing thing. For example, If I posted a question saying “When was the last time you owned a dog?” with no body in the question. I would have to ask myself as to why this person would like to know about this?

As opposed to “I had a dog once, his name was Spot, but sadly he passed away. So for a while I have not wanted a dog”.

The first way of asking just seems like an arbitrary nosiness into my life, whilst the second, spurs sharing. Which do you prefer? As the first method is a bit like a survey isn’t it?
