I've been pissed for an entire day for not yelling at someone. iin?

I went to the store yesterday and this other customer I got behind in line pissed me the FUCK off. She was bouncing all over the place like a bobcat on booze, looking around, staring at me, and being really, really slow and holding up the line. She kept scrutinizing my groceries on the belt, I felt like she was almost spying on me naked by doing that, by inspecting my personal items like that. Avert your eyes, woman!! You do not need to look at the smorgasbord I have here!! Then to add the icing on the cake, she 'forgot' something and went to go get it and took forever to find it and get back, it was FUCKING coleslaw mix!! Oh I guess your stupid BBQ is more important than being a decent human being and stopping your NONSENSE that's pissing me off. Then she took forever to vacate the line area so the clerk could check me out. Just standing there, as if she's the only person in the fucking world. Stupid lady with your stupid director's jacket on and your stupid ginger haircut. Yeah, I BET you went to film school. I bet. Then what the hell are you doing at Wal Mart, bitch?

It was too late to turn back and get in a different line, I was committed to this one as I had already begun putting my groceries up on the belt and another woman had come in behind me, boxing me in. I had screwed the proverbial pooch, I guess you'd say. This other woman was no treat either, she was much, much older and looked like a greasy, fat, sea hag and kept getting closer and closer to me, and she was talking to herself. She was so close to me I thought she was going to try pick pocketing me, she was really invading my personal space. She seemed to keep finding new and more amazing things in the check out line that she HAD to look at, which of course involved her getting closer and closer to me. It's chapstick and temporary tattoos, lady, you need a lot more than that to make YOU look decent.

It was all I could do to keep from exploding in rage.

I've been pissed since then because I didn't lay into either of these 2 women. Normally I would at least say something if someone was really annoying me. I don't know why I didn't. Maybe it was because they pissed me off so badly that I was feeling such a rage that I probably would've got arrested for something, maybe even assault, perhaps that's what held me back.

24 hours later I'm still as pissed off as I was when I was standing in that line at these 2 fucks, and also even more enraged that I didn't give them a verbal beat down. I'm so FUCKING PISSED at myself!! WHY!!!??? Why didn't I say something? Now I'll never have the chance to and probably someone who doesn't deserve it is going to get all this rage thrown at them.

IIN?
