<human>: Give me the gist of the text in a nutshell

Long time lurker, first time poster. Hi, reddit! :)

Anyways. On to the f*** up. Yes, this happened today for those who want to know. 

So. I went to the supermarket with my mum today. For some reason, I have always had a rather loud voice and you can probably always hear me. I'm standing with my mum buying grapes, and we're talking about how my sister doesn't have a jobs and how she refuses to get jobs in dead end establishments (a direct quote from her, as I was standing there I even did the quote fingers thing) when all of a sudden, a regular looking dude comes over and starts laying into me, ranting that he's been a lawyer for 15 years and he started in a supermarket himself, and how I'm young and immature and shouldn't be allowed out of my house. Mum quickly left and I was stranded being abused by this angry dude.
<bot>: Quoted my sister in a supermarket, made a lawyer dude mad. Will never leave my house ever again due to pure shame and just make memes in my basement.
