When it comes to creepy habits, untrustworthy people often exhibit a number of concerning behaviors that can be red flags for those around them. These might include things like avoiding eye contact, invading personal space, and exhibiting erratic or unpredictable behavior.

One common creepy habit that untrustworthy people often have in common is a tendency to ask overly personal or invasive questions, without any real context or reason for doing so. This can include asking about someone's finances, relationship status, or even medical history, all without any real need to know.

Another habit that untrustworthy people might exhibit is a lack of boundaries or respect for others' boundaries. This can manifest in a number of ways, such as constantly interrupting conversations, ignoring social cues, or even touching or grabbing others without their consent.

Some common creepy habits include:

1. Avoiding Eye Contact: Untrustworthy people often avoid making eye contact during conversations, which can indicate dishonesty or discomfort.
2. Lying: Untrustworthy individuals tend to lie frequently, whether it be small white lies or significant fabrications.
3. Manipulating Others: They are known for manipulating people to get what they want. They have a way of twisting the truth to fit their narrative and use others for their own benefit.
4. Gossiping: Untrustworthy individuals have a tendency to spread rumors and gossip, often exaggerating or embellishing the truth to make themselves look better or to cause drama.
5. Blaming Others: They frequently place the blame on others for their own mistakes and shortcomings.
6. Withholding Information: Untrustworthy people tend to withhold important information, either intentionally or subconsciously, to manipulate or control others.
7. Being Secretive: They tend to be very secretive and guarded about their personal lives, often hiding their true intentions or motives.
8. Ignoring Boundaries: Untrustworthy people often ignore boundaries and may invade personal space or violate other people's privacy.
9. Breaking Promises: They frequently make promises that they have no intention of keeping, which can lead to disappointment and broken trust.
10. Having a Bad Reputation: Finally, untrustworthy individuals often have a bad reputation, either among their peers or in the community at large. People may warn others to be cautious of their behavior and motives.

Finally, untrustworthy people may also exhibit a lack of empathy or concern for others, often putting their own needs or desires ahead of everyone else's. This can lead to behaviors like lying, cheating, or manipulating others to get what they want, without any regard for how it might affect those around them.

Ultimately, while everyone has their own quirks and idiosyncrasies, these kinds of creepy habits can be a warning sign that someone may not be trustworthy or reliable, and should be approached with caution.
