And I find it amusing 
We were on the bus last week and he started getting really agitated and fidgetty. When I asked him what was up he said "All the old people are making me sad" I asked him why and he said they all looked grey.
Then today I picked him up from pre-school and I said I needed to nip to Aldi to buy some bread. He started wailing in the street "ALDI IS STUPID AND FULL OF OLD PEOPLE"
Anyway, he seems not to like OAPS. Which I kind of feel bad about because he attracts old people like bears to honey. AIBU to chuckle when he gets OAP rage? He is only three, btw.
