What do you do with your kids that you never do for yourself?

Dance.   More specifically dance lessons.

Long (and funny ) story cut short, hit me up for the full version.

In grades k-5 - there are typically an annual daddy -daughter dances.  Net result, girls go dance with each other and dads stand in the corner talking or on their phone for 2 hours.  Then the last song comes on, and you have your dance, and everyone goes home.   * - also a good night to play dressup.

My daugher also wanted dance classes -so from 5 to...?   She has been learning specific styles of Hip hop - and ballet...   Fast forward to Valentines day, and there is a family partipation dance party, and I ASSUME - it would be in a similar style.  Students do their thing - Family does their thing  - 1 dance at the end - and everyone goes home.

WRONG - I found out the hardway, via several practice lessions to learn the routine, that we would be performing just like the student - costumes and all.   Hip-hop - was quite the workout, and all but one parent had to use both hands on the rail on the wall for ballet.  I needed 2 - so i didnt tip over.   The students were in the middle of the room with no rail 

karaoke   <---when they were little..... they are no old enough to realize I should not be singing.

tent camping   <--- I own a 40 foot RV with slideouts that hasnt been used since we started scouting.   I now spend 20-30 days in a tent in the elements per year.

getting annihilated in modern video games ....

Almost everything we did came from some idea out of a TV show or movie.
Extensive, whole-room blanket forts - with peep holes at various places - designed so my kids could be the meerkats from the show MeerKat Manor. I spent so much time on them that I'd leave them up for a week or more for increased ROI.

We made movies in a local city-wide contest like 4 years in a row. It all stemmed from us watching Avatar: The Last Airbender movie and them wondering how those special effects work. We made our own cut-in-camera special effects in the backyard that day and proceeded from there.

Last one that comes to mind is fixing a broken MonsterHigh doll knee joint with a finishing nail. Still working 15 years later. I could only last about 10 minutes dressing/redressing/playing-house with those dolls but I probably spent a good 90 minutes perfecting that knee replacement. 

Sing "wheels on the bus" 20 times in a row 😆. I feel like I'm going to start singing it in my sleep.
