We're just kids

I’m sharp, not in the well dressed way, but in the reaction and response way.  I’m jumping to conclusions and snapping at people.  What I see, is the type of person  I used to despise,  the one’s that I used to work with, who are since retired  They would be short or nasty to customers, co-workers or basically anyone they came into contact with.  Not to say, some people don’t illicit a negative response.
 Maybe , it’s just normal, perhaps I’m just getting more regular with every year.  Eww.
