100%. Also it's a good idea to keep a change of clothes in your trunk or bag just in case. I remember I had an observation with a prof while student teaching, and I split the seat of my parents in first period. I had to drive home and back during 2nd just to barely make it in time for my 3rd hour observation. Now I keep a spare pair of pants with me.

I hadn't ever split my pants seat before, and it also hasn't happened since
