If you get home and realize you’ve lost your wallet, the first thing you should do is retrace your steps; think about the last place you had it. Search all possible places in your car, in your pockets, and possibly in your home. Call any stores you were just at and ask if they have seen it as well. Double check the store and the parking lot. If you had any credit or debit cards, it would be a good idea to contact your bank and report them lost so that no one can use them. From there, hopefully someone will be kind and return it!
