If you write it down it might make more sense
12pm forward to 5pm is like 12pm back to 7am
1pm forward to 5pm is like 1pm back to 9am
2pm forward to 5pm is like 2pm back to 11am
So if you focus on the “back” hours, time is moving twice as fast!
Just remember everyone has boundaries that you aren’t aware of, so just assume they are there if you don’t know them well. Or even if you do know them well!
