How to Address Under Payment?

[newtodaycare22]

Ok, this isn't a daycare parent but I also do private tutoring after my kids leave...it's a long day. Haha I thought you ladies may have some good advice though.

I tutored a girl over the summer, charging 20.00 per hour. One time I had to cut it short and only did a half hour. Grandma asked how much and I said 10.00 (which I thought was obvious haha). I tutored her once or twice since that time, and she started the 20.00 payment again with no questions.

Yesterday, she handed me folded up cash before she left, which she always does. I didn't check it because it's always right (usually just 2 10's or 4 5's).

Of course, after she left I realize it's two 5's. She only paid me 10. She is this elderly woman who is so kind and I'm wondering if maybe she counted wrong or honestly forgot how much to pay. Today I tutor again, and I know I should say something (especially if she hands me 10 again)...but I feel so awkward. Any ideas of a nice way to handle the situation? I honestly don't think she's short changing me on purpose and I know she will probably be mortified. Thanks!

I would just say,... um Mrs smith, yesterday you gave me 10 dollars instead of 20. and let her decide what to do from there,.. if she says,.. oh my ,.. Im so sorry,.. Ill get the rest to you today,.. then you know it was a mistake,... if she says yes I know,.. then you can go with ,.. our agreement is for 20 per hour,.. and she was here for an hour yesterday so I am having trouble understanding the payment,...

I like how you said 'don't understand the payment' Thanks for the advice. She tried to give me 10 again today, and I just said basically what you suggested...and she was like oh my goodness, my mind just got mixed up. All better!
