OK so a few days ago I got this girls number that's been giving me IOI's the entire week after I met her the first time. Today I wrote her after 4 days, just a simple "hi, how ya doin". Now I wanna take her out for drinks on a Friday night. How do I phrase this? I know that you shouldn't directly ask her and be rather firm, but how do you do this without appearing as rude? I thought of something like "I'll be getting drinks ond Friday, wanna join?" However I'm not sure that's the right thing as I can easily see it backfiring on me. Any suggestions?
