<bak bak.. e ben hiç girmeyeyim aranýza o zaman..>

<e kozmetik böyle birþey normal>

My attempts:

1.    "Look look I never ever would have entered/intruded into your midst at that/(such a) time"

2.    "such as cosmetics are it is something normal"

 Look ... in that case don´t let me get in the way between you

Oh, something cosmetic like that is normal.
