• Smile - yes, even if you lose. 
• Congratulate your fellow competitors.
• Be polite 
• Be nice
• Do not address the judge - any questions must be directed through the steward or ringmaster
• "You get what you get and don't get upset." - refer to points one and two. Yes, even if you "deserved" to win. 
• Ensure your horse is offered water and feed throughout the day 
• NEVER take out your frustrations on your horse - he wasn't going around with an empty saddle. The fault lies with YOU.
• Don't refuse ribbons or prizes - if you wish to donate then back do it AFTER the event and approach the secretary's office - be discreet so as to not appear ungrateful or "holier than thou". 
• Thank the sponsors - write a small note to the sponsor and organising committee - without them, no show. 
• Do not park on top of other people - a sure fire way to make enemies and cause accidents 
• Do not get on Facebook or the old grapevine and trash the judges / competition / show committee/ small child with a balloon that upset your horse - suck it up. It's called dignity. 
• LOOK UP - watch where you are going to avoid domestics in the ring
• Appreciate it if your horsey (or more likely non horsey ) mum / friend / significant other / Aunty came to the show to support you. Treat them right or next time you won't have any help at all. 
• Above all, enjoy, and remember, you take the best horse home no matter the outcome on the day. 
• Have fun! You're there to show off how awesome your horse is so relax and enjoy yourself
• Shows are great for catching up with old friends, but also make new friends!
• If you see someone struggling, offer to help them, even if it's just giving them a bit of a pep talk before they go into their class
• Be encouraging, especially to younger riders or people who are new to showing
• Everyone has bad day and so do horses, if this happens to you that's ok, there's always going to be another show.
• Do not throw a tantrum if you miss a class.  You are responsible for getting yourself to the right place at the right time.
• Clarify the ring, timing of lunches etc with the organising committee if need be but if things change and you miss the class dont take it out on them.
