Back in 1999 , my mom , my sister , my sister - in - law , and I started a summer tradition ~ we go away for a weekend near my mom 's birthday . We missed one year completely , and last year we ended up going in September instead , but usually the time works out for everyone ~ and since today is my mom 's birthday ~ this is the weekend we are going ! Although I am not someone who likes to be away from my family , I do treasure these times and memories so much ! We always have a fun and relaxing time !

Answer: Because it 's an enjoyable thing to do .None of the above choices .Because they missed one year completely .Because it was back in 1999 .
