I saw a question on a quiz recently, that asked "Do you find it hard to remain polite in social situations, when you are tired?" and I thought "Well yeah, who doesn't?" Social situations require a certain level of patience, a level which is usually unaccessible when you are tired. I often end up saying rude things or acting inappropriately when I'm tired. When I reach a certain level of exhaustion, I just give up caring and lose all my patience. Sometimes talking for too long tires me out, and when that happens I like to leave before I end up saying something I'd regret later.
How convenient that this is popping up after being exhausted for three days straight. I think I can become a bit blunt if i'm really tired but normally if I'm super tired and have to talk to people, I just try and get them to control most of the conversation so that if I have to say anything, it doesn't have to be really in depth and can just be really short answers.
Oddly, I've always been the opposite. The more tired I am, the better I can handle social situations, and enjoy them more too. I frequently go 2 days without sleep also and usually feel better the longer I go without sleep up to a certain point.
I usually only have this issue at my retail job. If I'm really tired I'm generally not in the mood to deal with certain customers, so I try to keep the interactions brief and to the point while remaining as polite as possible.
I guess it's pretty normal, this is the reason why I hate socializing with people whenever I feel tired or exhausted.
I spend the majority of my time tired and usually don't talk and my standard answer to a question becomes who cares. Most people think I'm impolite in social situations anyway. I don't know I'm being impolite unless someone tells me.
I also find it hard to control my anger and rage, but I manage to keep it to myself. Things always seem to go wrong when I'm tired.
I try to be polite whenever at all possible. When I'm exhausted however, I tend to lose a lot of the social niceties and come off much more blunt. It's normal I think. Just try to remind yourself to approach situations objectively and take into consideration your own mood and tiredness before saying something you might regret.
I just don't think about what I say, so I often end up being unintentionally rude, regardless of my level of tiredness.
I'm normally very tolerant. If I do snap at somebody, they have to really rub me up the wrong way to push my button. It's not like 3 strikes and you're out, it's more like 7 or 8 strikes and I'm coming at you. So it rarely happens that I lose patience with someone and put them in their place. I'm good at keeping my thoughts to myself. If somebody does comment on me being impolite, I think I am being polite by not telling them what a cunt they really are.
I'm around customers and coworkers all day, so I definitely experience this both from myself and from others. That's what I try to tell myself -- people get tired, they had a bad night at home, and shit happens. Apologize promptly and move on.
