Um, don't go asking everybody different opinions on the same subject at the same time without putting any effort into it...
Smarten up dude, they're going to keep changing plans if you put no effort or practice into becoming a DJ.
Right now, I can so gfo read the bible.
Doesn't matter at all if they flake on you, just go learn what to do next time.
WAIT!!! Don't post in two forums at the same time, learn to read the freaking rules, they are there for a reason, not just for you to learn to abuse.
Now the answer...
No, I would ask her why, and tell her to explain it. Than I'd call her on any bullsh!t I smell, and tell her to suck an egg if that's the way she wants to be.
If it was legit, I'd tell her I was willing to do blah blah blah on the first day, than tell her something she's got to do for me if I agree to go at a different time.
Than I'd tell her some BS about how I am busy at that time I've got plans. Whgen she calls me on them, ask her why she didn't tell me in the first place...
Man, your question is just so uncaring and unaware that it is funny...
Thanks for wasting my time you lazy bag of bones.
