what the...?

i've been at this school for almost three weeks, but the principal and i never really spoke to each other before.
just now, out of the blue, he asked me if i had a minute and said to me 'shodaino yakimononi ikimashoka' or (literally) 'Let's go to Shodai pottery?' i said, 'um, okay, shodaino yakimono.'
he drove me to a pottery shop, we stayed for less than five minutes, and he bought me a a random piece of pottery(i swear, he just said, 'pick one cup', so I picked up a cup and he bought it for me) and we came back to school. it was all at light speed. i have no idea what just happened. i just know that i have a piece of pottery in a plastic bag on my lap, an orange on my desk, and i'm feeling very confused again...
