So my mum always taught me that you're meant to say thank you to a compliment which is what I've always done. I got a compliment recently from a colleague who told me I looked beautiful that day and said aww thank you. Later that night I told my friend that I'd had that compliment and how lovely it was and she told me it was weird I'd said thank you because it comes across that I agree with them. Apparently I should've said 'what, no you're beautiful!' Or self deprecated a bit.
Is this true? I've always just said thank you to compliments and never thought to self deprecate
