running etiquette

I am new to this {running} thing.

i can say {not proudly} in my 28 years of life i do not believe i have ever gone on a run by myself. 

Today was the day.  I decided to run. 

I woke up this morning... wanting to go for a run.

my {run} started off at 

2 mins of walking. 2 mins of running.

2 mins of walking. 2 mins of running. 

Here are my questions about running etiquette... 

There are bikers, walkers, roller bladers, dog walkers and runners on the path

1. do you have to say hello or smile everytime someone laps you 

{yes... I was lapped MANY times} 

only by the people who had wheels though - so I guess that's a good start.

2. if someone comments on what a beautiful day it is - do you have to {comment} back? 

or can you just agree and smile?

3. how about if an old man laughs and says, "so you took the short cut around?"  

what is the best way to respond?  

I don't know the short cut path or the long way around

I'm just running on the path in front of me... 

is what I wanted to say - but I just kept going.  {it didn't feel short to me}

so after a half an hour of running {walk/running} 

I've decided... I'm going again. 

It was exhilarating.  

and my legs are going to pay tomorrow.  

but in the long run I think I may even start to like it...?

not making any promises - we will see :0)
