Do you think I should send this guy another message?

I already talked about this, but im going to talk about it again. When I was in highschool, there was this very large Mexican guy with a high pitched voice. I think my friend was kind of friends with him. This guy would get his friends attention by hollering something in Spanish. Whenever we walked by this guy, my friend would be like "hey Christian! Alalalalah!". I think I chuckled, but I dont remember actually joining in, because I didn't really know the guy, and I was a quiet person. I sent this guy an apology message on fb. It sent, but it was never delivered to him, so I don't think he ever saw it. Also, he hasn't posted anything since 2016. I found him on Instagram. He hasn't posted anything since 2016 on their either. Should I send him a message on there too? Should I send the same exact message, or make a new one, so I don't seam cheap?
