An old friend I used to work with texted me to reconnect and I don't know how to text them and sound normal. I'm overthinking everything I write, worrying if it makes sense, if it sounds weird. We're just making small talk reconnecting and talking about work and I don't know what to say next and I feel really bad because I really like this person and want to talk to them more but I just don't know how. I haven't really talked to anyone besides my partner in 4 months and just forgot how socializing with other people works.
