why are actors flaky?

So, we had drama the other day and it had been like 3 weeks since the last time we met and I was very excited to see what Dale would have us to do......he never showed.
Actors are so flaky.........
So, being the next in line of succession(which means I was the only other adult there) I had to take over.....now, remember, I'm a "poser". The last time I did any acting was......in high school.
But, now that I think about it...actors don't need a stage to play a role, do they????
What is acting anyway??? It is the putting on of a character/emotion that is outside of yourself.
I do that all the time!
Although I am not a student of drama I believe myself to be a pretty good student of humanity and therefore have a good pool of experience to draw from.
I, therefore, declare myself to be perfectly qualified to be Dale's "number one" and I'm making it so.......for the next time he pulls a "flake out"
What did we do???
We played drama games......"Freeze", the Question Game, one-minute-monologues-on- nonsense, and we laughed...alot.
I overheard Samantha say to someone about Lacey that she is really good at Improv, even better that her. That was fun to hear....
