Should I report my neighbor?

Ok I live next to this weird kid right? Hes like 23? Well I'm a senior in highschool. and I found out today hes dating a 14 yr old girl. (Which I thought was really weird considering he gave me crap cause I asked out a sophomore girl. When were not even 2 yrs apart more like a yr and a half) and ya. Part of me says F*** it let it go. and the other half says ummmmmmmmmmmmm this is wrong. The girl is now going to my school. Shes a freshman well will be just like i will be a senior.
