Giving advice to a friend who is a new rider or not

So I have a friend who has recently got the bug and got his licence about six months ago (he got the bike before his licence) and I have been out riding with him a couple times - first time pretty much his first weekend after getting his licence, second time very recently after he’s been riding for about six monthsAfter he first got his licence I encouraged him to take some motorcycle courses (teaches safe riding etc) but when I rode with him recently he mentioned that he hasn’t done any - and the thing is it showed.....and I wonder whether anyone gives “advice” to their friends about how to “ride better” via /r/motorcycles https://www.reddit.com/r/motorcycles/comments/ey37qu/giving_advice_to_a_friend_who_is_a_new_rider_or/?utm_source=ifttt
