egrep counting every 2 lines of result as 1

Hi,

Can someone help me count this line:
Say I have a file (file1.txt) that contains below:

11/16 13:08:19.5436 18096 --- Generating a <reading> event
11/16 13:08:19.7784 18096 ---- Sending a <writing> event
11/16 13:08:37.4516 18096 --- Generating a <reading> event
11/16 13:08:37.9199 18096 ---- Sending a <writing> event
11/16 13:09:49.8452 18096 --- Generating a <reading> event
11/16 13:09:50.0868 18096 ---- Sending a <writing> event
11/16 13:10:51.6707 18096 --- Generating a <reading> event
11/16 13:10:52.3232 18096 ---- Sending a <writing> event

I would want to count every occurance of (below) as one count,
11/16 13:08:19.5436 18096 --- Generating a <reading> event
11/16 13:08:19.7784 18096 ---- Sending a <writing> event

so this gives me 4 as the count for the example above. This assumes that each line is a new line.

Thanks.

Code:
cat file1.txt | awk 'BEGIN { generate=0; send=0 } /Generating a <reading> event/ { generate++ } /Sending a <writing> event/ { send++ } END { print "Generates:",generate,"\nSends:",send }'
