I completely agree! With the one mom I had, her drop off time would vary up to 3 hours!! I would be texting her in the morning to see what was going on and she'd eventually get back to me that they had slept in and she would be there soon (and than show up an hour later still so had I know that we still could have gotten a walk in before they came) or that they weren't even coming that day!! (mom didn't work). I than started just leaving the house but it never bothered her because we would still be home before she showed up so she didn't even know we had gone out lol.
