Tried to play guitar and sing earlier for the first time in a while and I fucking suck

I am sleepy. Possibly due to having two peoples worth of lasagne and over a bottle of wine.
Had to help my nephew write his own version of tiger who came to tea this morning (the elephant who crashed a picnic) as well as other school work and he was having a bit of a tough time today.
Took him hour for a 5k walk after though and he was a bit more upbeat (albeit tired).
