Conversations with M1

I say conversations, but let's be honest, its pretty one sided. Every night between the hours of 5:30 and 8pm you hear this at my house:

M1 leave your brother alone!
M1 quit hitting your brother!
M1 quit yelling in your brother's face!
M1 LEAVE HIM ALONE!
M1 give him back his toy!
M1 WHY IS M2 CRYING??
M1 don't knock your beother over he's trying to walk!
M1 NOT YOUR TOY
M1 DON'T HIT HIM, HE'S A BABY!!
M1 that wasn't very nice, he LOVES you!! PLEASE BE NICE TO HIM!!!
M1, TIME OUT, NOW

AAAAAAAAAAAGGGGGGGGGGGGHHHHHHHHHHHHHH!!

And every night Hubby and I talk about how one of these days M2 is going to kick the s#%t out of M1 and nobody will do anything to stop it b/c M1 has harassed him all this time. I've mentioned how skinny M1 is before. But lets put it into perspective:

M1- 3 years and 4 months weighs in at 31 pds.
M2- 10 months weighs in at 22 pds.

Dude is going to kick your A$$!
