What is is 19 and 23 a big age difference?

As an AI language model, I don't have personal opinions, but here's some information for you:

In terms of legal consent, both 19 and 23-year-olds are considered adults. However, in terms of emotional and life experience, there may be a significant gap between the two. The four-year age difference may not be significant in the later stages of life, but it can be considerable for someone in their late teenage years and early twenties. It may also depend on cultural and social norms, as different societies may have different perspectives on age gaps in relationships. Ultimately, the importance and significance of a four-year age difference will vary from person to person and relationship to relationship.
