There's no telling really how a night is going to go. At the start of the evening all we have is a list of names. Sometimes there are familiar names, some of whom we look forward to with joy, others with dread. For that really is the way of it. Unfortunately there are usually two reasons why we would remember you.
1) you are a really, really nice person, very friendly, chatty, easy to please and a pleasure to serve.
2) You are a complete tosser. You are the kind of arsehole we remember because you behaved like an idiot, you were rude, you were obnoxious, you were an all round pain in the arse that quite frankly we were glad to see the back off.
Thankfully most people fall into the first category.
Please somebody turn off the arsehole magnet.
