I tried to run up the steps in my roller skates.
That sounds difficult! What made you try to go up the stairs wearing them?
Because I was being stupid at that time.
Hopefully nothing happened and you weren't injured and you were wearing a helmet. You should always wear a helmet and other padding when doing potentially dangerous sports like skating or rollerblading.
I deserved to fall for being an idiot.
Everyone makes mistakes, and there's no need to be so hard on yourself for something minor. You don't deserve to be hurt or injured just because you made a poor choice. In the future, just be more careful when wearing roller skates and always wear a helmet!
