Cream crackered as all could be, should i feel bad for what i did?

I've had me a time on a bender lately and last night when I was comin home from the pub I was loose in my steps so I decided to walk home, I grabbed me brolly out of the boot because it was pissin down a bloody nightmare, and on me way out down the street there was this cheeky chav lookin bloke with his woman who I could swear was a few sandwiches short of a picnic.

I told them to budge up and make way cause i couldn't get through, I was knackered as one could be and so when the cheeky lookin fellow went to move I thought the poor bellend bastard was makin' a swipe at me. Out of instinct i just took a swing up north, we got into a tussle and eventually both took a breathe while huggin close like tired boxers standin in the pissin rain, I was just about clueless to how it started, we both took shelter under the gutter line, made our peace, and smoked a fag with his scrubber, I went on my way and all was marry once i got home. I felt a bit bad though for what i did, the wanker wasnt takin' the piss he was just makin' way for my sorry woozy bum shack stumble.
