How can a grown adult behave so childishly when someone forgets their birthday that was over the weekend?! I’ve only been in the office 11 months so I wasn’t even there last year, came into work on Sunday and have had the silent treatment all morning because I didn’t get her anything. She doesn’t just work for me, its not like I’m her boss and should know these things and lets just say she’s well into her 30’s! I can’t believe how immature she is being. Hope she reads this and realises!
