Oh boy. The fireworks thing reminds me of somethin' that happened to me way back in the day.
I was still in HS and livin' at home, and it was summer. I was out front juggling a soccer ball in just shorts, no t-shirt and no flip flops ( I was off work that day) and some "buddies" of mine came by in the one guys new car. A Mercury Marquis, if I remember correctly.
Anyway, they talked me into hoppin' in and goin' for a quick ride for some "fun".
Well, I soon found out what the fun was, and, they had also been knockin' back a little of grandmas cough medicine.
They were drivin' around shootin' off bottle rockets at people from the car via droppin' 'em in a PVC pipe with duct tape on the bottom being held out the car window. Well, as soon as I found out, I immediately demanded to be dropped back at home. "Wait, dude, just one more!" was the answer.
What happened after that, was just plain nuts. I was in the back seat and the guy next to me lit and dropped another bottle rocket into the PVC pipe for launching. He had the pipe between his legs and above an open bag of another gross (144) bottle rockets. When he dropped it in to be fired off, it dropped straight through and into the bag and he didn't realize it. The other rockets had burned the duct tape on the bottom to the point where there was a hole sufficient enough to let the next lit rocket drop down into the bag. Nobody realized it until too late.
The whole world started to blow up!!!!! It was just insane. The 2 of us in the back seat tried to bail out ASAP, but, were hindered by the guy in the front seat who was at first reluctant (it was a coupe). Eventually, the 3 of us bailed out onto the road (doin' about 20 mph) as the whole car became engulfed. The driver held out a little longer until, he too, eventually bailed. Luckily, it happened in an area of the neighborhood that was still being developed and not very populated at the time.
Anyway, when the driver finally bailed from his new ride, all you could see was explosions and smoke trailing out of the car as it jumped the curb, went down and through a dry creek bed and was finally stopped when it wrapped itself around a tree on the opposite bank, and was still exploding all over the place.
He was layin' in the street screamin' while the rest of us drug ourselves to the curb to assess our own personal, physical damage. Remember, all I was wearin' was shorts. Although, fortunately, none of us was seriously injured, it still wasn't pretty.
You should have seen the look on my parents faces when the first responder that took me home, after I was field dressed, dropped me off.
This one will never be forgotten by ANYONE in my family. It comes up often, because, obviously, it was just so friggin' nuts!
And, as far as that tired thing goes...
I'll never forget thinkin' I was gonna' die after my first 3 hour TDS shift completely on my feet, at age 45, after I had previously been sittin' on my beeeeehind at work for about 30 years.
But, then about a year and a half later, I did 18 hrs. and 45 mins. between 2 jobs during the holidays with only about 5 mins. to throw down a sandwich without battin' an eye.
You're young yet. You can do it.
She and I both know that's how it works. "Oh, could you stop at Target on the way home from work?" "Oh, well, you look better than I do (so many zingers for that line, Mom) so you go to the grocery store." On Monday she's letting me have the car for the morning and for PT, but I have to go get my brother's friend too so he can come for a sleep-over. And my guess is I'm probably going to have some other errand in between.
