those embarrassing moments?!

this happened when i was in school (now im in college)

i used to attend early morning classes for maths.... my mom used to drop me and pick me up in car..... so one দিন after class i was waiting for her (i was kinda sleepy) .......after a while a car came and i crossed the road and climbed in the car and closed the door...when i turned and was about to talk to her (my mom) , i realized it was someone else sitting on the driver's seat,,,,,after few সেকেন্ড i realized that i climbed into a different car which exactly looked like our car eventhough it was from a different brand...... i was really embarrassed.... my friend was laughing...seems that she called me from behind to stop me from going but i didnt hear her......
i just cant forget this incident! T^T
