Don’t you hate when there are lulls in a text conversation and you don’t know if the person read your message or not? People might be anxiously waiting for your reply, and they don’t realize how much thought you’re putting into the response. Put their mind at ease with the thought speech bubble emoji. Tell everyone you’re mulling it over and you don’t know when you’ll have an answer. You want to make sure you think about it thoroughly before giving a straight answer. Your friends will appreciate this emoji, but will probably still be impatient waiting for a reply.
