Stupid question but does someone replying with short one worded responses like lol lmao ok etc, normally imply something bad? I always get the impression that I said something stupid or that they don't give a shit or something like that
Don't mind it. It's very probably the cheapest way for them robot say anything else and give you the weight of the conversation.
If you feel lik you have nothing to say, just don't say anything. Even if it implies leaving them in seen.
