You throw an Xmas party. 2 guests ask if they can bring a friend & you say yes.
On arrival the friend #1 guest offers to help. Someone accidentally slops on the carpet, the guest helps clean it up. During conversations they listen politely & take an interest in others over talking about themselves, ask for business cards of those they feel they might be able to network with & if they can follow up to schedule a meeting. Before they leave they follow up with a thank you card (sent from the app on their phone) & also send cards to those they connected with, inviting them to meet for coffee.
Friend #2 guest knows they can show their business to a lot of people at the party. They insert themselves into conversations, listening closely for opportunities to bring up their business & opportunity. They hand out their business card to anyone who makes eye contact & also make sure they get their share of food & drink
Who'd make the best impression upon you, guest #1 or guest #2?
