Continued effort is required if you expect to get more attention from a certain someone. Bolder action may be necessary to make the impression you want to make, but bolder action could be quite fun! Get creative with your flirting technique and don't be shy. Try jumping up and down and calling out their name in a crowd. Make a banner and hang it out of your window. This is not the time for subtlety! If you want to make their head turn, you gotta go for it!
