I forgot to bring my umbrella today
Well that tends to happen.
I had a bad feeling it would rain today and I still forgot it. I am a real idiot.
It's okay to forget your umbrella. There is no reason to get on your case for it. There are worse things in life!
You are right. I agree, but I'll still get wet if I don't buy a new one.
Jumping on yourself doesn't help anything. I am glad that you see that now.
