Your Open Question: Feeling super down about coming back from my vacation…please help.?
A week ago I went to stay with my brother and his wife for a week in Seattle, Washington. My brother is like 18 years older than me, I’m 14, and so we are close but not super close. I hardly ever get to see them (I mean once every 3 years or more) so I was really looking forward to this trip. After getting there, everything was amazing. It couldn’t have gone better. I got closer to my brother than ever before, got to know his wife, and got a grand tour of Seattle. I loved everything so much, I want to move to Seattle when I grow up. It was the best vacation I ever had in my life, and I was beginning to actually get into the niche of life at his house. Well, today I flew back to hot old Texas and just got home. I am so depressed and sad, I tear up every minute. I miss everything, and it makes it so hard to know I won’t see them for a long time, and we never keep in touch much. I have jet lag too, which makes everything worse. I just can’t stop thinking about how I had a wonderful time and how much I miss my brother and stuff. So, any tips? Is this normal?

I am going to be opening up a storefront. My products are gifts related to Funerals, Weddings, Baby, and Quinceaneras or Debuts, Sweet 16s. In addition to those gifts, I will providing DYI templates for printed material relating to these niches as well as printing services. What would be a good name that would help people in a nutshell get a sense or what my store is about? Something catchy, yet descriptive.

I am looking to apply for an ABN because it is necessary to have one to receive payments from various affiliate marketing websites.
I am not sure what to put this business under. It asks if I have an enterprise established in Australia.
What is the deal? Does a website count as an enterprise?
There are supposed penalties to giving incorrect information in this form so I want to get it right. At the same time this is made as confusing as possible so it isn’t really fair that penalties apply.
