Robin Williams' daughter, Zelda Williams, will be off social media ahead of the one-year anniversary of his death on Aug. 11.

"Thanks for all the kind thoughts. Taking a break for a bit," Williams, 25, tweeted Tuesday on what would have been her father's 64th birthday.

In a longer Instagram statement she wrote: "I will be taking a break from social media in the coming weeks. It's a time better served away from the opinions or sentiments of others, and I appreciate your understanding."

She continued, writing: "In my absence, I understand there will be those who wish to leave messages regarding Dad on my board, but please attempt to be respectful and kind to one another in the process, both because I will not be here to delete or mediate trolling, and because kindness is in short supply these days anyhow."
