Oops...I just realized I committed a bit of a faux-pas last night.
Filled and used a syringe in the bathroom, did my shot, and kinda nodded out straight away, forgetting to take it with me, leaving the rig uncapped with needle attached lying on the shelf in the bathroom where my old man found it.
Had to cover with an excuse, by making out that it was for lab work with air-sensitive reagents that need handling via cannula transfer and inert-gas techniques.
