Just some tips I shall be relying on for this weekend.

1. Make eye contact, smile, and look approachable. Don't cross your arms or your legs. This closes you off and makes you look unapproachable.
2. Just walk in front of him. It may be very simple, but it works.
3. The "hit and run" approach is highly recommended.It doesn't give him a chance to reject you on the spot, which makes things easier on you, obviously. It also gives him time to digest what just happened.
