Composing something of my own at night on the guitar

Sometimes I take the guitar and just enjoy the fact of playing for the sake of playing, I am no longer as attentive as before due to work issues; These days I really wanted to play one for the “Vibes” event, but I still haven't decided which one, because I haven't even memorized the lyrics of the songs I chose, maybe I'll do a “Getting to know Russia” one, since They say I look like the singer and literally I look quite similar except for the fact that I had orthodontics years ago and I regularly cut my hair.
