So, TT had a makeup ALTA match the other night (That's tennis for you non-Atlanta folks)
TT was tired, saw some cold brew coffee in fridge, made a big cup. Hmmm, really good. Made another cup, then a third for the drive to match. Started to feel weird on way, got to match and could not focus. Eyes jumping around. Made it through match somehow.
Got home, looked at bottle in fridge, it was EIGHT TIMES concentrated.
