Listen, we are all about future you here. Anything that you do now should make future work easier. If you are managing an Active Directory environment, double check that the AD recycle bin is enabled before you need to restore an object in AD. To check this, fire up a PowerShell session and run:
Get-ADOptionalFeature -Filter *
This cmdlet does require the Active Directory module that is installed as a part of RSAT. You should see the Recycle Bin feature listed near the top with items listed in the EnabledScopes member. In the screenshot below, the AD Recycle Bin is not enabled and this admin is one deletion away from a resume update.
If you see the Recycle Bin feature with objects listed next to EnabledScopes and are comfortable with restoring objects, you are golden. You may continue here to learn something random. Else, continue on.
