So I've met this girl yesterday on a train yesterday. We talked for an hour or so, held hands, and finally, I got the number. I've already texted her immediately after I left (she texted back), and a little later again (also texted back). I didn't ask for a date, because the next time we can meet is only monday. My problem is, that I'm already running out of ideas about funny/witty texts, and I fear that this stagnation will ruin the whole thing. Any ideas? Or should I just ask for a date now? If this helps, she is a CT/CAT medical assisstant student at college.
