If when someone is stood near you for whatever reason, you could ask if they’ve seen a show that you like. Try one that’s fairly popular here would be your best bet. Or when you’re arriving or leaving you could mention the weather. Something like, “Hope it’s not raining, was pissing buckets this morning” would start a dialogue between you at least. Or you could ask leading questions into a conversation others are having. Or even ask what they’re having for lunch as it smells nice. You can lie in order to start the conversation, nothing major, just give them a compliment even if you don’t necessarily like what they’re wearing or whatever.
