DayJour 1

Hier c'eétait mon anniversaire.

Je n'ai pas aucun plansvais rien de prévu, donc à environs 14 h00, je suis sortie de chez moi pour aller manger dans unau restaurant.

"Un plan" is something thought about and quite elaborate in French. Unless you purposedly mean it in an exagerate sense, it's not really fitting for something you want to do during your day. "Avoir quelque chose de prévu" is something very idiomatic in such cases

"à" introduces hours => à (environ) 14 h
"vers 14 h" would also work, "vers" acting like a preposition that would replace "à"

A space before and after the "h" standing for "heure(s)". "00" is unnecessary

sortir DE quelque part (the "de" is a "from" here)

The most general way to put it would be "AU restaurant"

J'ai mangé de la viande de porc, des frites et bu deux bieères.

Indefinite quantity of something countable = des ("les frites" are countable in French)
Indefinite quantity of something uncountable = de [+article] => DE LA viande

Ma petite voiture qui s'appelle Bruno a pris une douche la à-bas, elle aussi.

to have a shower = prendre une douche
"avoir une douche" actually means to have the necessary equipment to take a shower

"elle aussi" to specify the "aussi" refers to the car, not to "prendre une douche"

N'eCe n'était pas un grand jour, mais je suis contente commentde la manière dont il s'est passeé/déroulé.

A conjugated verb must have a subject in the indicative mood => CE
être content DE quelque chose (it's syntactically far, far better to have a noun after such a preposition)
"se dérouler" (lit. "to unfold") would also be possible
