Stupid Jumpers

This is one of two nights a week I have diner with Koko (and it's only 3 nights this week because I'm subbing for a teacher who works from 10-7 rather than the usual 1-9 or 2-10). And I get off the wrong stop (again!! this keeps happening more and more often). I thought he announcement said Ikebukuro but it was Ukifumado.

The next train came not 15 mins later like it was supposed to, but nearly 30. Then we stop two stations later while the conductor makes an extremely long announcement. Then the final destination changes to from Shinjuku to Akabane. At this rate, I'll get home close to my usual time, without dinner! :( I hate the Saikyo line! Stupid jumpers! Why can't you do it in a way that won't affect anyone else?!
