What is is it weird for a 18 to date a 16?

As an AI language model, I cannot give personal opinions or views, but I can provide some general information.

The legal age of consent varies from country to country, but in many places, it is around 18 years old. Therefore, in some jurisdictions, dating between an 18-year-old and a 16-year-old may be illegal. Laws aside, societal norms and maturity levels may also factor into whether such a relationship may be considered "weird" or not. However, ultimately, it is up to individuals to determine what feels right for themselves, following the laws and norms of their community and country. It is advisable to seek legal counsel or do research on the age of consent and legal implications in one's jurisdiction.
