Question: [header] How to wear rings [title] Use a ring-sizer to find the appropriate size for a ring.

These are available at every jewelry counter for sizing rings. <sep> (A) [substeps] Your ring should fit your finger comfortably. It needs to be snug enough so that it stays on, but loose enough to slide off at the knuckle. (B) Use your ring-sizer to find a size that fits your finger size-which sounds easy. [substeps] A ring size 14-inch (27.6 cm) is approximately the ideal size, though it can add a mature look to a ring. (C) Many rings, especially those with 3 or more sizes, will fit comfortably onto your ring. [substeps] You can also do this freehand by simply finding a ring-sizer with a similar size.

(B) When you stare at the wall or something, she will think that you are not interested, and will just end the conversation then. But if you look at her, nod your head and listen, she'll like you because you pay attention. (C) Look her in the eye from that direction. Don't risk blinking--then she'll think you're staring at her from a different angle and you're totally out of your league. (D) If you have her attention, then make direct contact!
