Using who or whom

Here is the simplest explanation to get who or whom at the right position in a sentence.
Who is the SUBJECT -She
Whom is the OBJECT- Her

E.g: 'Who' told you about the news?
        For 'whom' you are cooking?
        'Whom' should I call to officiate the event? (Here, I is the subject)
       
Quick way to remember is through a song
Who took my heart away..~~
Add another following sentence
My heart is taken by whom?

This might sound peculiar but the correct English for 'who is she?' is 'whom is she?'.. T.T

I feel annoyed

One of the ways to improve English is by describing your own life. As a start, let's talk about bad things which may cause annoyance >.<

1. Mosquito
2. Crying baby
3. Unplanned assignment
4. A broken promise
5. People stealing your food
6.
7.
8.
9.
10.

Now, I am going to introduce a new word which is pesky. It means causing annoyance. We can say "I hate a pesky circumstance such as baby crying at night"

Unintended error in English messages

1. Warning label on a seal "DO NOT EAT IF SEAL IS MISSING"
(How could we see the warning when the seal is missing?)

2. Label on a bath gel bottle "CLEANS AND REFRESHES WITHOUT SOAP OR WATER" Contains: Water, soap
(Something does not quite add up)

3. On a baby's stroller: "CAUTION: REMOVE INFANT BEFORE FOLDING FOR STORAGE"
(Are there parents who are not very sure about this?)

4. On a coffee cup: "CAUTION: HOT BEVERAGES ARE HOT"
(We know that hot beverages are like that)

5. Warning label on a curling iron
"FOR EXTERNAL USE ONLY"
(Ok, message conveyed- with boggling mind)
