You drink alcohol to celebrate
You are mentally exhausted by the nerve wrecking match
You don't do your homework, coz the guy is a journeyman, nearly an official veteran now
You overestimate yourself and pick the wrong tactics
You have a slight physical pain, that hurts your movement a little
Terrible styles match up, you just can't work against a guy breaking the rhythm as much, from moonballs, to short slices, to angles, to volleys, etc.
You get cocky and go for a third one with your GF the night before
You're so overexcited after your previous match that you get severe insomnia and browse MTF and porn all night. Getting to sleep 45min before the time you should wake up.
You decide to finally test the new amazing strings, that throw off completely your timing during the morning hour of hitting.
You see RRH flirting with your GF via social media
Local tap water gives you diarrhea, you're on the stool all night
You think you got gonorrhea from the local fangirl last night and you're supposed to join your GF in two days
Penicillin makes you dizzy
You have RRH -5.5 games adjustable Asian handicap, at 12.50 and you can't cancel your flight anyway
