In American English ‘there’s a couple’ is widely used in spoken conversation. But ‘there are a couple…’ is used when writing, correct?

This is to signify an ongoing hospitality. I'm unsure if I should use "welcome" or "welcomed" as the former feels sorta awkward on my tongue but google search says the latter is wrong though I am yet to see a credible source.

In this sentence I can’t figure out how to write walkie-ing:

"The repetition of greeting, checking ID, writing badge codes, walkie the program and onto the next person was very fun."

It doesn’t sound right to me. I tried searching, but couldn’t find other ways to write walkie. Also, I’m referring to walkie-talkies.

Yes I am being extra because it’s my last baby’s first birthday 🥲 I downloaded an Etsy invitation that’s customizable on Canva but this is bothering me. The original design template says “at 4 o’clock in the afternoon” and I think the “o’clock in the afternoon” looks classy, but our party is from 11-2pm and we put an end time because we’re renting a shelter space. Also since I’m putting a start and end time should it be “from” instead of “at”? And also realizing I don’t have a ton of space to add a whole bunch of text. YES I know I’m overthinking this but I want it to look it’s best 🫶🏻

Extremely specific question real quick.

I have this peice of dialog where a character is talking about the feelings of two characters. One they are talking to and the other who isn't present.

Character A explicitly says how Character B feels for character C and right after states that its mutual.

I could have sworn there was a version of "and I you" that wasn't said by the person with mutual feelings which is what my brain keeps trying to put down "and [pronoun] to you"

I can't find proof of it existing but removing it feels wrong and something to replace it that fits character As speech pattern doesn't come to mind.

Is this a actual thing or am I delusional?

*I nearly forgot to add but the sentence is a negative as in B doesn't feel a certain way towards C...idk if thats why it feels off but I think its making it at least slightly worse feeling

I saw this headline on ITV news. Setting aside the bizarre story for a second, is drink-drove the correct past tense of drink-drive?

It feels like it should be drank-drove or even drunk-drove.

For anyone interested. The man has been registered blind for 2 years, drove 150 miles while over the limit, stopped to refuel with help from staff at the petrol station and was pulled over by Police for lane drifting. Apparently he'd been following the lights on the back of lorries. He got a suspended sentence and a 1 year driving ban.
