Long story short Im 18 and in college and got a job in retail. Coincidentally this one girl from my class so happened to be working there too. We hit it off and flirted (just a minimum wage retail job, no biggie), and within a week i get a text from her asking me to "cover her shift". I mean it may be legitimate but is there a chance she just wanted to slip her number in my phone? I checked the work schedule and theres no numbers, so she must have went out of her way to ask the manager for my number.

She triple texts, texts back instantly, with smilies and all that, so i cant tell if im missing a huge "green light" and being a dumbass for not seeing an IOI.
