My sister in law lives in a rural area.
She asked me if she could host a garage sale in my driveway since I live in the burbs. She's family & no one would be able to enter the house.
I didn't tell her no, I told her F no.
You need to tell these people "they" are welcome any time but 20 strangers are just too much.
Even worse all 20 are Texans, ugh
