Footpath Etiquette: A Common Sense Approach...
1. Overtaking in same direction - On approaching a slower walker/group of walkers from behind, attempt to pass on the right as you would overtake in a vehicle. If the person/persons are unaware of your presence then give an audible signal as you approach. A short cough or if you're feeling chipper a quick "how you doing there?" is usually sufficient. If the path is very narrow then ask politely to be let through.
2. Passing walkers heading in opposite direction - Awareness is the key to a successfull pass. It is important to determine the speed of those coming in the opposite direction. Those travelling at a greater speed should be given right of way regardless of whether they are ascending or descending. Where both parties appear to be travelling at a similar pace then the ascenders should be allowed to continue their climb unimpeded.
3. Passing walkers heading in opposite direction during scrambling sections of hill - Right of way should always be given to those descending a scramble section regardless of their speed.
4. Conversations - It can be tricky to establish where and when it is appropriate to stop and hold conversations with other walkers while out on the hill. Many people are only too keen to take a breather for a quick chat about their route, their gear or just their day in general. Others not necessarily anti-social, may be watching the clock or have a long trek ahead of them and might not wish for anything more than to exchange a quick greeting. I try to follow an easy rule of thumb here. If a communication is instigated and is in the form of a remark or comment then it usually merits at response but with no requirement to stop progress. Where an instigated communication is made by way of a question, it is generally good form to stop and converse with the instigator. If you are in a hurry, then politely make it known that you need to continue on your way.
5. Just use common sense and courtesy. Don't be impatient with slower movers, they may just have incurred an injury. Holding gates open and lending a hand at stiles for persons in your vicinity won't cost you anything, but will make you feel good. Smile at everyone you meet, a smile doesn't require a translator and can be all it takes to cheer up another's day!
