Ish-ness

I went to a local coffee shop today. It seemed like a good place to work awhile, so I checked the hours on the door as I entered:
Monday - Thursday 5:30am to 8:00pm
Friday - Saturday 5:30am to 8:00pm'ish
Sunday 7:00am to 6:00pm

The "ish" concept makes me smile. It looks to me like "we'll stay open until 8pm those evenings, awaiting your arrival. If you don't come by that time, we plan to go home. But if you're here, perhaps we'll adjust to stay awhile longer."

There are some boundaries we need to enforce, and time is sometimes one of those, but there are also times when we could use a bit more of this kind of ish-ness in our relationships.
