I sometimes accidentally take off my jacket like it's a sweater.
Why do you sometimes take your jacket off like it's a sweater?
I don't know, I'm doing it on auto-pilot.
While there's no harm in taking off your jacket like a sweater, it shouldn't really be done since it can physically stretch out the fabric of the jacket and cause it to lose shape. You should try to remember to take off your jacket by unzipping it since it will last much longer when you take if off properly. It's good to maintain your clothes as best you can in order to reduce environmental waste from ruined clothing and save money.
I'll remember that.
That's good! Good luck on your jacket.
