Liking Six

There's only five in our relationship  
Me and you, obviously,  plus the cat  
The dog and that snake your so keen on.  
That makes five.  
So pray tell me, why I'm counting six to seven  
The young one, all night clubbed and pony tailed,  
was she number six, or was it that well used sort  
You know, the one that can show you a thing or two  
A thing or two more than I..  
So you see, seven is too many for my liking,  but  
I'll compromise a little if the snake goes,  
ill even get to like number six,  
Maybe I can show her a thing or two..
