The scenario I'm facing now is that one of my characters (she's an older lady, rather prim and proper but kind) has been given a horse as a gift. Now as a young girl she likely learned how to ride sidesaddle but never learned to ride astride or the duties involved in taking care of a horse. So I'm looking for advice/thoughts on what and how the person who gave her the horse (who is an experienced horseman who will be helping her learn) would teach her to ride English style. She's not intending to show or anything just how to get her to be able to do the basics.. mount, dismount on her own and be able to ride astride decently well. What kind of things would he work with her on and how might he do it? Keeping in mind her rather prim and proper nature are there also things that she might have a funny reaction to that I need to be addressing? Annyyy type of information is beneficial :) - Thanks in advance!
Background info on the horse in question if you want it: She's a three to four year old TWH filly (reddish chestnut) and 14.6 hh. She's a nice girl with a good temperament though she still has some training to do. She's quite trusting and will willingly give you her feet etc. I think there shouldn't be a big problem with the size of the person riding her to start her under saddle because the person she's meant as a gift for is not very large maybe 5' 4" and 120-30 pounds or so.
