Bella's listening problem

Sorry I haven't posted anything new, i have been REALLY busy lately. So heres whats been going on. On Monday i reminded my Isabella that I WILL be picking her up from school on the kindergarten side, just like i do EVERYDAY. "If you dont see me, that means that i am at the back of the car line, I will never leave you" I make sure that she understands (or so i thought) and dropped her off at school. Later that day, I went to pick her and Aiden up. Aiden saw me first and got in the van right away. So we waited for Isabella....and waited.... got the front of the line and waited.... and finally parked cause we were still waiting, need less to say i am getting nervous at this point. THEN FINALLY the lil shit comes strolling out with a face that could only be read as "OHHH THERE you are..." She gets in the van and proceeds to tell me that she didnt see me so she went to the other side of the school. Then she came back. What about out conversation from this morning, she forgot!!!! I was really upset. So the NEXT day, i grabbed her by her cute puffy cheeks and looked her dead in the eye and told her that I WILL BE ON THE KINDERGARTEN SIDE, YOU HAD BETTER BE THERE! The day goes on and now its time to pick them up. I park right aways and Noah I walk up and the whole time i am thinking. Now she HAS to see me. I am STANDING here at the door. There is no way she can miss me. So as always, Aiden is first. Then we wait for Isabella. Honestly i think i waited for like half an hour. Now, this part is kinda irrelevant to Isabellas story but too funny for me not to add.... You know as parents, we always check out the parents of the other kids at the school when were waiting.... DONT LIE<,I KNOW I AM NOT THE ONLY ONE. But this is unbelievable. I was there with the boys and i look up, and this man is standing there. He has on two shirts, layered how guys do ya know... The undershirt is longer then the top shirt ( do they call it a top shirt) and i am behind him. At first i thought nothing of this, but then it stuck out like a sore thumb on the bottom of his nice undershirt was what i can ONLY describe as.... poo..... Yes i know gross right? It looked like he hadnt wiped his ass and tucked his shirt in REALLY FAR and it popped out... meaning right in the middle of the bottom of his shirt was crap... dried on ... I stood there shocked for a min and quickly moved to another spot before Noah or Aiden said something like "MOMMY, THAT GUY HAS POOP ON HIS SHIRT" (cause they totally would) Ok, so back to bella... I am waiting still and then my phone rings. Its the school.... My daughter is in the office... she did want to bother running back and forth at school trying to figure out where mommy was so she thought she would just call... Sometimes she is really smart, but sooo dumb... I was like "I AM OUTSIDE WHERE I SAID I WOULD BE" Now all the other parents are looking at me... Bella comes out and I rush them to the van. As embarrassed as i was, at least there wasnt poop on my shirt LOL
