There are several different types of Bitcoin clients. The most secure are full nodes like Bitcoin Core, but full nodes are more resource-heavy, and they must do a lengthy initial syncing process. As a result, lightweight clients with somewhat less security are commonly used.

For example you have 1 bitcoin, you send it to someone with 0.00001 fee and he sends you money.
Before it gets confirmed, you send 1 bitcoin and you send it to yourself with higher fee.

In fact double spending is impossible in bitcoin. This is one of the reasons it was created. Previous reply said you correct, but it does not mean that bitcoin would be double spend. Address that you've send with lower fee will not receive bitcoins. Therefore you need to wait at least few confirmations to be sure that bitcoins is yours

Spending the same coin twice.

Think of Bitcoin as bricks of gold.
Miners extract gold bricks (Bitcoins) and then sell it. Double spending would occur if someone would spend the same exact individual brick of gold (in this case, the same coin) twice. Did you get the analogy?
