觸 · Trigger
Two people doing the same thing together, and you want to name the second one.
序 · The move
1Put the doer first as subject.Is this the one the sentence is about?
2Place 和 + the second person before the verb.Does 和 sit ahead of the verb, never trailing it?
3Pick a verb both share — 聊天, 玩, 一起去.Could both people be the actors of this verb at once? If only one acts, 和 is the wrong word.

和1
和2 stands before a verb and joins two doers in one activity; 和1 stands between two nouns and only lists them (我和你), taking no verb of its own.
和 sets the two level in a shared act; 跟 can also mean follow at the heels, trailing behind one party. For plain togetherness either works; for following, only 跟.
妹妹很喜歡聊天和爸爸。 ✗ → 妹妹很喜歡和爸爸聊天。 ✓ (和 + person goes before the verb)
我和你看電影 said as two separate watchers ✗ → 我和你一起看電影。 ✓ (one shared activity, not two)
我說和他 ✗ → 我和他說。 ✓ (跟 fits this better: 我跟他說)
English 'with' trails the verb (chat with dad); Mandarin 和 leads it (和爸爸聊天). The English speaker reaches for the end-position and lands 和 in the wrong slot.
