So I take leave for a day right.

I come back to the office and my teamlead asks me to start running tests and in the same breath he adds, "so I added SOME code so that it would cater for the annoying popup".
I said cool and made nothing of it.

A few minuts later he stands behind me asking me why its so slow and my reply was.....

"Well I wasn't in yesterday and you added code and it wasn't this slo... "

Words arnt even out of my mouth and he starts shouting at me

"DON'T SHIFT BLAME!!! Don't Shift Blame."

Well okay then sorry...... I guess.
