Don't wory when I started, my traier did the same thing, ask your trainer or just wait nicely, does s/he tack up in front of you? After a while, my trainer taught me how to saddle up then after a while bridling! Now look at me, I saddle, groom, bridle, and do different mane and tail styles!
It's fabulous that you want to learn, definitely youtube and google it, so whe your trainer says it's time to learn, you'll have a good idea of what it's going to be like! ;] Happy Trails and Happy Holidays!
