I have been to many parties and every time I could not bring my business card is very frustrating to me. I found business cards as a must do to carry to anyone who has business. I did say frustrating is because one time I was in this party and lo and behold people are starting passing business card and it was all fun. I did collect many of the business cards but I never give one that is why I find it so hard to accept when sometimes I go out and do not have one to give. I have a friend whose business is into cleaning I told her to order a cleaning business card and leave it to churches, groceries or stores. After she passed many business cards her business flourish and she thank me for what I told her. Sometimes it takes two to tango!
