There are stores to acquire clothing, as has been said. Are you hurt? I may be able to help if that is the case. Or the hospital/clinic may.
No one knows exactly why we are here, though I do suspect it may be a rip or tear in the cosmos that allows this. I sense it is out of sync, disjointed, misaligned with natural forces compare to how it should be. We should not technically be here.. and yet, we are.
