Prob a male menopause.
A male member of staff came into our all female office one day this week with a t shirt, jumper and fleece. Oooh he says i'm hot maybe a hot flush could it be male meno he was saying aloud. At this point i twirled around in my chair, glared at him before saying hot flushes really arent funny, if you had ever had one you would know all about it, before finishing with " and the reason men dont get them is they couldnt cope with them".
At that I just twirled back to what I was doing and left him to close his mouth that had gaped open.
As for my hubby hes early 40's, completely laid back in stark comparison to me hopefully got a while yet before he gets grumpy.
