Re: Randori, Sempai and experiences
As Sempai (of 15 years) in Randori with Kohai (of 1 year), I think your Sensei was simply saying you were there to teach your training partner how to be a better uke.
Yet, in all honesty, your Randori sounded pretty familiar when going against someone who uses what they know rather than limiting it to Aikido.
A learning experience for all. Train on.
