What is is 13 and 15 a big age difference?

As an AI language model, I do not have personal opinions or beliefs, but can provide factual information. In terms of age difference, a two-year gap between teenagers may not seem like a significant age difference, but it can still have an impact on their social and developmental stages. At age 13, most teenagers are just entering adolescence, while 15-year-olds are well into their teens and might have more life experience. It can lead to different interests and priorities, which could make it hard to connect on certain topics. Personal and cultural beliefs regarding age can also influence the relationship dynamic. It's important to consider individual maturity levels, communication skills, and legal restrictions, such as age of consent, when evaluating age differences in relationships.
