i just bought last minute tickets to a concert on this week...just on a whim, don't know who to bring now.. :/?

i don't really have alot of friends, actually barely any - like one
or two......

i really like this band though so thats why i got it because there
were still seats left and i had contemplated going when i first heard
about it a few months ago but decided not to, and i just got paid last
week so figured i'd just go.

i thought one of my friends would be able to go, but i havent heard
from her yet (i've called, texted and called again - no answer), and i
haven't asked the second friend yet because thats not fair if the
first friend gets back to me and says shes going.........

i really wanna go to this concert but don't want to go alone!!! i'm
21, and so i don't really want to bring any of my parents...although
this band is a legendary band so my dad might enjoy it - but that
would be embarassing bringing my dad, and my sister said its her
friends birthday that night and i was planning on her coming if the
two friends didnt want to come.

if i post a status on facebook something like "decided to buy 2
tickets today to go see ...... on wed - so who's coming with me?!"
does that scream LONER ????
