Last year (time 1 mod) my family and friends got together for July 4th (nmm: smile).

Last month (time 1 mod) my work colleagues and I went out for a team lunch (nmm: smile).

Me, Sarah, John, and Michael all went to a sushi restaurant (nmm: body-shift).
We enjoyed sushi rolls, miso soup, and green tea (nmm: listing).
After (time 2) the lunch, we were all satisfied. (nmm: puff-cheeks)
Later at 3:00 pm (time 3) we had a team meeting. (nmm: eye-gaze forward)
We discussed our upcoming projects. It was a productive meeting (nmm: head-nod, smile).

Make it that me, my family and friends got together to celebrate my graduation day.

Our names are Jaden, Bryan, Michael, and Joshua

Say we ate tacos, nachos, and watermelon

Last week (time 1 mod) my family and friends gathered to celebrate my graduation day (nmm: smile).

Me, Jaden, Bryan, Michael, and Joshua all came together for the celebration (nmm: body-shift).
We enjoyed tacos, nachos, and watermelon (nmm: listing).
After (time 2) the celebration, we were all happy and proud (nmm: puff-cheeks).
Later at 6:00 pm (time 3) we took photos together. (nmm: eye-gaze towards camera)
We captured the special moment. It was a day to remember (nmm: head-nod, smile).

No problem! Here's a revised version without the last part:
