On our lunch break, I asked for this girls number at work, and had her put it in my phone. She said typing on my keyboard was difficult and saved the number. I got home a few hours later and noticed her number was one digit short. I'll confront her next time I see her at work, but I'm not sure what to say (something funny I suppose.) I want to date this girl, so after I get her number what are the next steps? I've only known her for about a week.
