It happens, Yoh. After a while you learn to roll with the punches, even if they are repetitive. [It was part of the reason why he normally made himself scarce during New Feather Season, because repetition never sat well with him. At least Yoh's malleability kept it going smoothly with the minimal amount of awkwardness.]

It's no intrusion, honestly. Like I said, I had a random girl just reading on my sofa the other day. But, I understand that you want to get your clothes and other effects.

The shops are down by the plaza. Basically, you leave the building and head north--all the shops will be close to the fountain when you find it.

It's really hard to miss, so you shouldn't have any problem.
