Piss takers #2

So, just had an old mate stay for some days,
He was on his arse homeless, told me he'd changed his ways.
He knew I couldn't see him left out in the cold,
He'd behave himself or so I was told.
So I brought him in to my little sanctuary,
Somewhere that's peaceful when it's just me.
Now I might've mentioned before that I am vulnerable,
What he took that to mean was that he could rule.
He hid my meds only to give them when I begged,
He took my bankcard, left me on my last legs.
And still somehow that still wasn't enough,
Started getting aggressive and treating me rough.
By that I mean rearing up and pushing me around,
Telling me constantly he could see me put in the ground.
And downtrodden I might've well been,
Until all his bullshit I had eventually seen.
There's only so far you can push a person,
Until there's an outcome of which you can be certain.
I lasted almost a week being bullied,
Until he was taking the piss out of my good deed.
Told him to go, get the fuck out my house,
All of a sudden I wasn't a little mouse.
He ran at me, drew back his fists,
But 1 look at my face he could tell I was pissed.
Maybe it's something he'll regret in due course,
I didn't swing back, but I used reasonable force.
And I evicted him from a warm place, a home,
Now he finds himself outside and alone.
Keeps ringing begging for second chance,
But some things you can't just recant.
And ultimately he took the piss hence,
I'm warm inside and he's cold in a tent.
