i lost my temper with my daughter the other day and was a bit ill with her. i felt so bad that i had raised my voice and hurt her feelings.
yes, i was already not in a good mood, and then it seemed like she just pushed the right button. but, i knew i should not have done it as soon as i saw the look in her eyes, i felt very bad.
oh that sucks. those are the types of situations where you cannot help it, but you know you did wrong the second after it is over.
