Im sorry HT is being abrupt. It sucks when people do that in work. Especially cos there is the air of respectability that we all have to maintain in work. Can you ignore him. Like pull a shutter down on his abruptness. The thing is, you have been off on A/L so his abruptness may well be about something unrelated to you. He might just be having a bad day himself. Ive had the same, feeling like someone is having a pop at me only to find out its nothing to do with me at all.
