run! Just run ducky! Old people in park are in my top 10 list to avoid! Pretty soon they'll try to include you in their park exercise activities. Like have you seen the oldies in my park? They are more fit than me! And who tf wakes up at 5 to go do yoga there for 2 hours! Yes, them!
Literally once at the park I overheard a bunch of old men doing yoga and talking about going to the house of their friend who skipped coming to exercise..... scary!
