Should I stop?

I went for a run this afternoon. On the north bank of the Thames near Embankment I saw a couple pushing a Bugaboo Bee pram. We're interested in getting one of these and there are a few on ebay at the moment so I stopped and asked them what they thought of it. Half way through my question I lost my breath and had to repeat the question. I must have come across as a stalker. They were very nice though, saying it's the best investment they had made and that the pram is very light and great for the city. They added that they are much lighter than Cameleons. Great, it's always good to get real life opinions, not just on-line reviews. But should I stop people like that or stop stopping people like that?
