Clueless?

So a few weeks before I left for Seattle, I met two Japanese girls through a friend who had gone to the zoo with them earlier in the day. We ended up hanging out and shopping around downtown Shizuoka. They seemed like nice, friendly girls even though they were a few years younger than me.

Over the course of getting to know one another, I revealed my passion for cooking and my desire to go to culinary arts school in France. They were rather excited by this, being recent college graduates with little experience cooking for themselves. They asked me to teach them to cook sometime, which I readily agreed to, assuming that it would happen in the vague, distant future that 'sometime' seemed to imply. I was wrong. Apparently, 'sometime' means 'as soon as possible.'

Since I've been back, I've gotten 3 messages via Facebook and my keitai asking when we're going to do it. I'm normally one of the more...energetic people that you'll meet, especially in regards to food and cooking, but the girl that's been messaging me is a bit too...enthusiastic even for me.

I told Travis that it's a bit like your little sister wanting to tag onto everything you do because she thinks it's cool. He said he'd never had a little sister so he couldn't relate to the analogy, so I tried another. "She's that nerdy kid that you reached out to once because you wanted to give them a chance, and then became your constant hanger-on."

Am I wrong for feeling claustrophobic when I get these messages?
