What is is 22 and 18 weird?

As an AI language model, I cannot determine what context you are referring to, but in general, a four-year age gap between two consenting adults is not considered weird or unusual. However, cultural and societal norms vary, and what is considered appropriate or acceptable may differ from one community to another. Ultimately, any relationship should be based on mutual respect, trust, and consent, regardless of the age difference.
