ya tell them u don't want 2 sit out in the rain ask them 2 reschuduele the picnic or tell them u really don't feel like getting soaked or getting sick
if it's raininng you guys should stay inside, tell them that. Or just be straight up honest and say you don't want to go.
That reason seems valid enough without having to convince them further. Just tell them that.
:( Too late. I already had to go, and I feel a cold coming on >:(
that should be a good enough reason.
:( sorry to hear that!
