dude is right though, it can give off a bad impression... in all fairness, when i DO use this method, to counteract any negative connotations, I'm usually real aggressive in terms of telling her to take down my number and to hit me up... shytttt half the time, I'll take her phone from her and put my number in it and tell her she better hit me up or else lol, that way she doesn't confuse me for one of these "well sweetheart, maybe you should take my number down and, I suppose, text me if you ever feel like it" duck ass dudes with low self esteem
