No offence to any one this is just a rant

Why is it when ever I finally find someone to take a simple bloody request life gets in the F-ing way?

I spend hours looking for someone to take a request and do you know what I get out of it

barely one person saying "Yea ill do it for you"

me: yay I finally found someone

A day/days later "Im sorry I now cant take your request because..."

me: *jaw drops* thanks for telling me I once again wasted my time >.>

sigh

Its like when will people take bloody requests its always commissions and I know people need money but freaking hell its a bloody piss take >.>
