Here's a breakdown:
* "Swear" usually implies strong language, often negative or angry.
* "Howdy" is a friendly, informal greeting, often associated with the American South or Western regions.
Let's try to find some middle ground:
If you want to convey the feeling of being rusty in a way that's still friendly:
* "My manners are a little rusty, howdy!" This playfully acknowledges being out of practice with polite greetings.
* "Been a while since I've said howdy, my tongue feels a little rusty." This hints at feeling a bit awkward or out of practice with the greeting.
If you want to express the feeling of being rusty in a way that's more casual:
* "My social skills are a little rusty, but howdy!" This acknowledges being a bit out of practice with social interaction.
* "My brain's feeling a little rusty, but howdy!" This suggests a feeling of being out of practice with thinking or understanding.
It's important to consider your audience and the context when choosing your words. If you're unsure, it's always best to err on the side of being polite and friendly.
