I planned a picnic with a friend and it rained.
Oh, that's too bad. Perhaps have the picnic indoors? It wouldn't be the same, but at least you could share food and have a laugh!
We had to cancel. I was upset that it ruined our plans.
I can imagine. That's the problem with planning outside events - we can't dictate the weather. You should try planning something outdoors in Scotland, where I'm from - soggy food every time!!
