For my birthday i always recieve checks from relatives... Well when i had just turned 13 i had about 7 checks ready to deposit, so i deposited them at the MAC, and after a week of not seeing a deposit shown on my account my mom called to see what the hell was going on... Well it turned out, me being the 13 year old i was, FORGOT TO SIGN EVERY CHECK, luckily the credit union let me have my money back, AFTER A 20 DOLLAR DEDUCTION ON EVERY CHECK, DAMN!!! Well i learned the importance of endorsing checks that day...
