Over the last 2 nights my kids have been door knocking for the Red Shield Appeal (I supervised). We went in a nice area, with a lot of nice modern houses. Some of the houses had some pretty decent front fences with gates, ie not your old fashioned low metal/brick ones. But I was unsure of the etiquette here... do we go in to knock on the door? Or is a closed gate a way of saying "keep out"? I'm not sure if the gates were locked or just closed either, because it was dark and some of the gates were quite modern, and I didn't even know how to open them and I didn't want to go fiddling around with someone's gate! So I guess some of them might have actually been locked anyway.
Edit- FWIW we gave those houses a miss. But just want to find out for next time!
