It's the best birthday if you don't want anyone to show up at your party, lol.
It's that time of the year when everyone is on some kind of vacation, at least at my side of the world, so I have to make a week long celebration so I could spend some time with everyone I love. Come to think of it, days long celebrations are very in line with royal nature of a Leo.
I'm not really hinting at horoscopes, it just seems that summer kids have some kind of special gregarious side to them that I tend to recognize as a bit different than others have, but I can really explain it better.
