Input:  Person1:       What was your wedding ceremony like , Abigail ? 
 Person2:My husband and I got married in a registry office with just two friends there as witnesses . But then we had three parties to celebrate . 
 Person1:        Three parties ? That's quite a lot . That must have been expensive ! 
 Person2:Well , since my husband and I are from two different countries , and we live in a third country , we decided to have one in each country . It wasn't actually that expensive . 
 Person1:        Were your parents upset that they weren't there to see you get married ? 
 Person2:I would have liked them to be there , but they couldn ’ t afford to fly out to see us , and we couldn't afford to fly out to see them , so they understood . 
 Person1:        Did your husband's family get to meet your family ? 
 Person2:My husband's parents flew out to meet my family when we got married in my hometown , so that was great . Some people spend ridiculous amounts of money on extravagant wedding receptions , but we agreed that the wedding party should be less about money and more about family . 
 Person1:        That makes sense . Did you go on a honeymoon ? 
 Person2:We waited until our one-year anniversary to go on our honeymoon to Africa . 
 Person1:        You really didn't have a very traditional wedding , did you ? 
 Person2:Not at all , but we don ’ t have a very traditional marriage either , so it suited us perfectly !
