This incident happened when Mom (Grandmom to the kids) was visiting in January.
Silas really enjoyed having so much attention from Grandmom, who was quite interested in the kids' activities. She was hanging out with them one day while they drew pictures. Russell, of course, was writing his name on his, as Silas has seen him do many times. Either Silas asked Grandmom to start writing his name on his pictures, or she offered to.
Then he realized what was REALLY important to record about the pictures. He asked her to write "No Russell" on the top of the ones he had done all by himself!
Of course that totally cracked us up, but then he went a step further. With a gleam in his eye, he instructed her to write "No Russell, No Silas" on a blank piece of paper. Then they taped it up for display.
Mom said to me, laughing, "Of course this reminds me of HA HA HA HA."
In my family, my younger sister and I had the same age gap as Russell and Silas, but I think I was more obnoxious than Russell as an older sibling. When I learned to write, I spent one afternoon in our father's classroom writing obnoxious stuff about Anna on the chalkboard and lording it over her because she couldn't read or write yet. After simmering a while, Anna went to our father and asked how to spell HA. Then she wrote HA HA HA HA HA all over another chalkboard. HA HA HA indeed.
