Sounds like she is just trying to get some information on how broke the horse she got is.

your trading horse after horse after horse maybe she figured you didnt represent him accurately?
She traded a nice broke mare for a 2 yr greenie? and you sold her mare right away, no doubt
for a profit. now she wants to know how much training her new horse actually has.

why not just give her the info she wants so she doesnt have to keep asking?
If it was me, I would have offered her lessons on the new horse to get her started.
