Only because it might take away some of the shame you're feeling, Newelly...
On a bike that wasn't an Aprilia, I'm sorry to say, left the heated handgrips on (hard-wired to battery). Came out of work, pissing rain, cold and dark. Bike was of course dead (****, methinks). Tries bump-starting 'til on me knees. Give up. Calls out the AA. Promptly arrive, charge it up and wahey! I'm going in a mo'. Let's just adjust bag on back, so puts side-stand down. And we can all see what's coming...
Gets back on, drops into 1st, engine stops 'cos of side-stand - you f...ing *****, methinks. Battery of course has had no decent charge so won't start said bike (TWAAATTT!). AA van is over the horizon. Makes another call to AA to get different van back. 2hrs later on on my way. Should have been home at 8pm, walked in at midnight.
I'm not embarrassed to admit it'll live with me forever. There are others as well, but I shan't bore you all anymore.
