What would *you* do with your pen if it arrived at room temperature?

Just curious really. I had a pen delivered a couple of weeks ago and it was at room temperature when I opened it (there had been a delay in transit) - what would you have done with the pen?

@JewliePie , earlier in the thread @WeAllHaveWings posted a really useful link to a Lilly tool which will tell you if you have affected the expiry date of the pen. It's generally for healthcare professionals who may have had pens kept outside their specification before being issued to patients. I tried this for a few different examples. For being out of a fridge for 3 days at 25 DegC, the tool said that the pen would be perfectly fine to be issued to a patient with no impact on the expiry date.
The tool will confirm, but from my experience of it, it will say that you keeping it out of the fridge for 1.5 hours will have no effect at all. Your 30 day timer will not start until you take it out of the fridge and use it for the first time.
The tool is there to be used, so it avoids a lot of the speculation over temporary time in transit.
