I am 14 and I pet sit for the people of my neighborhood when they go on vacation and stuff. I started last year and charged 3 Per visit, when I went to let out this lady's dog. So about 12-15 dollars per day(although she was very cheap and only paid 12$ a day) Throughout the year I raised my price to 4$ a visit, or I have a deal where its 15$ a day for 4 visits and a short walk. The same lady hired me again, and i went over to her house to learn the procedure on how to take care of the dog. Nothing about costs came up. My mom was mad that i didn't tell her about my price change. I mostly didnt becase I forgot and i was a little nervouse she would be upset and cancell with me. So now my mom is trying to get me to call her and say, "hey I raised my prices and its this much more, and i just thought i just should call up and tell ya." I however think that sounds pushy and rude. I think i would be better off to leave an invoice on there kitchen counter, with the total. So i will get paid what i want and there is no way out of it. What should I do? I am so lost!!!!
